Example 3 : A small lantern of mass 100 gm is hanged from the pole of a bullock cart using a massless string.                      What is the tension in the string,                     (a)   when the bullock cart is at rest,                     (b)   moves with uniform velocity of 3 m/s                     (c)   moves with an acceleration of 2 .                      Assume that cart moves smoothly. Solution:   (a)   At rest :                                                               (b)   Uniform Velocity  (Inertial frame) :                                 No acceleration acts on the system. So.                                 Here also     (c)   Accelerating frames :
