Hello all,
I was going through study of gravitation of earth. The book teachs that gravity of earth is more near poles than at equator as earth is not perfect sphere rather radius of earth is lesser near poles larger at equator. A thought came in my mind that if the water at level goes also...
What is "that way" I would like if you write it in more open way instead of saying"that way", I mean what will you say how we treat infinitesimal small displacement to come up with definitions of torque and angular momentum as told by you?

Hello all,
First of all I want to mention what believe or result of concepts, do I hold about rotational motion especially about the angular velocity. I assume that unlike velocity angular velocity has to worked out from some point. I will begin with particle for this I assume that the question...
So should I say that finite angular displacements are neither scalars nor vectors(here risk is that my students will ask in what category are they fall and questions like what is the name of that category etc fall upon me :)) )
Or should I say it is controversial matter just remember that they...
Yeah that's where I need endorsement I mean I now agree that finite angular displacement doesn't obey commutation law I still don't feel confident in saying that, by not obeying commutation law by the finite displacements they are kept out of the category of vectors.
Thanks both of you, very well explained.
Though this has been explained very well I just need endorsement about the statement, that finite angular displacement is Scalar and infinitesimal small displacement is vector? Can I say it to my students or does this is a valid statement amongst the...
Hello all,
I am having hard time to know if the finite angular displacement really a scalar quantity?
In some books they say angular displacement when finite is Scalar and when infinitesimal small is Vector, with direction perpendicular to plane of circle government by right hand rule.
I...
Diamagnetic materials have their magnetic moment due to spin and there is no net dipole moment due to orbital motion of electrons. In any material having dipole moments due to orbital motion of its electron, many dipoles cling together in same orientation for reasons explained only by invoking...
Dear all, I know the sources of magnetic field are moving charges or varying electric field. I also know that subatomic particles(even neutron) have their own magnetic moment due to its quark and spin and their magnetic moment is explained by invoking quantum mechanics(though I don't know how...
Ok thats good. Can you suggest me some(or better only one best) book(s) to me for learning more about error analysis in measurement?
I have one another function( no so complex) where I need to write expression for error. Can I ask?
I know what is standard deviation, but what is standard error and Wolfram Mathematica things I don't know.
I would like if you could take me to the target point as easy as possible but if that's not possible unless I study special statistical methods than thing is different. In that case I...
Can you please elaborate I am not good at these statistics so that I can figure out the differences of details of statistical deviation and systematic deviation.
I really want to know it from the core. :)

This is giving me some thought but what if the rods are made not only in the same factories but also in the same mould under same conditions. I mean isn't it possible that they are identical?
Why?
Can you give me an example as it will be more helpful.
I am very happy to see you all helping...
Yeah I am thinking that, if you put 3 billion next to each other, you can measure the distance to the Moon with the same uncertainty(though I am not challenging that I am thinking correctly). I am considering that error is not linked with my calibrations(faulty calibrations or something) so it's...
I think I need to focus on what they are asking, when they say what is the length of two rods; and I think what they are asking is "what would you report when you place two rods end-to-end to measure it's length with the scale?"
And for this I think the maximum error should still remain the...
Hello all,
I am in a total state of confusion with regard to this. Here is question.
The length of a rod is [11.05 (+/-) 0.2]cm. What is the length of two rods?
I want to know should the answer be reported like
[22.1(+/-) 0.2] or [22.1(+/-) 0.4].
Regards:)
I have no problem in using in parallel axis theorm, however what I fear is that taking torque( F* perpendicular distance) and angular acceleration about a point other than the axis of rotation, would make equation inconsistent, since(as what I am thinking) the angular acceleration of the...
Hello all,
These days I am studying rotation and rolling of bodies. We know a body can be made to rotate about any point. Let's assume that an external force is acting on the rotating body fixed about the point of rotation, and this force made the body rotates faster that is its torque produces...
Exactly.
The problem is, the complete passage of question is not mentioning any assumption but just solved ignoring how (less)adhesive force can affect the answer.
Below is the example problem with its solution:

Hi everyone,
While studying surface tension I came across a(numerical example) problem which asks to find the force required to pull a circular glass plate of some given radius from the surface of water(assume plane of plate on water surface). Value of surface tension of water is also given in...
I am getting what can be called "something close to explanation", a clarity could be attain if some data is employed and use maths in it to fully understand , why the peak is most conspicuous at 54V. Can this be shown?
Thanks for your continuous support.
Regards!
I looked at their paper, but some of the terms they are using are not known to me. I would be thankful to you if you help me understand the point being explained through figure 10(attaching figure below) which settles my curiosity of knowing the matter asked in the post.
Regards!
