Resolve all the forces in X-Y plane as such where you might select axes inclined as per ur wish. Then Normal force acts normally to the surface and is equal to the forces acting normally towards the surface. Now put equilibrium condition.. For 3, i assume they are attached. the firststep...

I think you hav got the problem, and cahrge on each elemnent of the stick is Lam.dr.

find the treasures distance in vector form, take north j and east as i. Then also find the position vector of the place you reach through yellow bricks. Suntract the position vectors. The way to fnd second pos vector is rcos at i and rsin at j

My idea is from the fact that field is 0 internally at that point. So there must be two opposite vectors due to these two parts which must be equal in magnitude. But proving them separately using integration is becoming a bit difficult.

Please help me prove - A uniform spherical shell mass is cut into two pieces parallel to one of Symmetry axis. Prove that the gravitational field intensity due to the mass at the centre of the cross sectional plane parrallel to the symmetry axis is same for both the parts.

Let the Centre of AP be M, then MP is the radius Vector I guess from what I understood after seeing the picture. You know the co-ordinate of A and P, so you can find the co-ordinates of M.

Acceleration is rad/s^2 while the velocity is given in rev/min. Otherwise there is no mistake.

Can anybody here please explain to me about the spin of an electron in the covalent bond? My textbook just says that it follows the Hund’s rule. Moreover I am confused with one more statement in the text – it says that in a covalent bond, in the bonding molecular orbital the electrons tend to...

The path made by the outer wheel is a bit more than the inner wheel in the circular path becoz the radius made by it is more. I mean it is 1.6m longer than the radius of the inner circle due to the length of the axle. So the distance covered by the outer wheel is greater than the inner wheel for...

you have already told that you know how to calculate. Please show your work if you need a homework help. But I assume your question is to understand the science behind it. This is as per the law that - heat gained by the cold body is heat lost by hot body - a result of energy conservation...

On what axis will the object rotate? How do we measure torque? I would appeal for a bit more clearer information of the question.

Just think about what a-zero equation represent? what does a zero-equation physically mean? Since you have simply asked this in Maths column, I am asking you to consider this in a co-ordinate system. Now what does their differentiation of that mean, like z = f(x, y).

Let a be the angle made with their initial velocities along the direction of final veloctitis. Now, v*cosa + v*cosa = v/4. Thus cosa = 1/8

Sorry. The second sentence is - the component of their initial velocities along the direction of final velocity must thus be same and add upto v/4

The components of their initial velocities perpendicular to the direction of their final velocity adds to zero. And the components along this direction must thus be same and add upto v/4.
