Question No. 32
A small spherical ball of mass 'm' is used as the bob of a pendulum. The work done by the force of tension on its displacement is W. The
same ball is made to roll on a frictionless table. The work done by the force of normal reaction is W2. Again the same ball is given a positive
charge 'q' and made to travel with a velocity v in a magnetic field B. The work done by the magnetic force experienced by the charged ball is
Wz. If the displacements in each case are the same, we have :
0 W, > W₂ > W3
O W = W2 = W3
o that WW2, W3 cannot be related by any equation
OW, <W₂ <W3
