Question

A particle is moving in a circular path with constant speed V. when its angular displacement is 120 degrees then change in its velocity is ---

i)V/2 ii) (root 3 by 2)•V iii)V iv) root 3 • V​

Answer 1

Answer:

The particle starts from point P and after half rotation, it reaches at Q via path PMQ.

Distance covered by particle to reach at Q is d=πR

Answer 2

Answer:

Distance covered by particle to reach at Q is D = Rπ
