infinite means no end on both sides semi infinite means which is fixed at one point and other point is not fixed eg line infinite and ray semi infinite

try it with energy method you would be albe to solve it. if not reply i will post the solution.

i think this might clear your doubt more then ask.

your acc was incorrect hence your answer came out wrong.

easy question pal i have solved it and i am placing the pictures. First find net force which is force on wire by current and field and second is frictional force which will rotate it and hence net force is IwB-f which is Ma . Then find torque which is fr=Iα when you will sove net acc. to be...

see there are two types of rolling one is accelerated and other is non accelerated in accelerated a=rα and other is v=rw. in v=rw relative velocity of pt.of contact with ground is 0 hence no friction force. but force is acting then balance a=rα. Want to read a book then i will suggest you to...

one thing every one says that our (any) galaxy is hundreds and thousands of lightyear long and also they rotate about their center then if they rotate with very low angular velocity then also the velocity of the extreme will cross the light speed? will it just think nd reply... (v=ω X r)

you can use the direct formula which is based on conservation of linear momentum and Newton law of restitution (e) its a propert of colliding materials

Rotation, rolling and sliping are different when you apply force on centre of wheel radius from center is zero and hence there is no torque as torque= r X F. and if r is 0 hence no torque and no angular acceleration means no change in angular velocity hence no rotation. But it starts rotating...

well if want to solve in real world then you have to consider drag force of air which will act on both x and y component and if wind is also blowing then it will effect the answer more but in ideal case as there is no acceleration along x direcion so dv/dt is 0 so velocity along x (v0 cos(angle...

If your question is different than this wirte the question properly and i will solve that and reply it.

The question is really simple you are thinking it much than its required solve within the wire and you will get counter emf and differential of it with length will give you E vector. I am giving one example to show how to work for these problems.

no i don't want to make money these are my parents words they say all about money. in reality i want to study the concepts of nature and this universe i am totally fascinated by physics role in nature and i could know the reality behind everything by science(physics) not by superstitious belief...

How much do physicist earn cause i want to be a physicist. My parents and friends want me to taks CS as my subject and do B Tech. They say a CS engineers earn around (160,000-300,000)$ a year. And they also say there is no scope of a physicist in India. Well I am confused so help me. I want to...
