Question

A long current carrying wire, carrying current such that it is flowing out from the plane of paper, is placed at O A steady state current is flowing in the loop ABCD

  1. the net force is zero    
  2. as seen from O, the loop will rotate in clock wise direction along axis OO’    
  3. both 1 & 2 are correct    
  4. as seen from O,the loop will rotate in anticlock wise direction along axis OO’    

The correct answer is: both 1 & 2 are correct

In figure, a particle is placed at the highest point A of a smooth sphere of radius r. It is given slight push, and it leaves the sphere at B, at a depth h vertically below A such that h is equal to

If v velocity acquired at B, then v2=2gh The particle will leave the sphere at B, when mv2rmgcosθ 2ghr=g(r-h)r, Which gives h=r3
