MCQ
A particle moving with uniform speed in a circular path maintains:
  • A
    Constant acceleration
  • B
    Constant velocity but varying acceleration
  • Varying velocity and varying acceleration
  • D
    Constant velocity

Answer

Correct option: C.
Varying velocity and varying acceleration
c
A particle moving with uniform speed in a circular path maintains varying velocity and varying acceleration. It is because direction of both velocity as well as acceleration will change continuously.
