MCQ
A car moves on a circular road. It describes equal angles about the centre in equal intervals of time. Which of the following statement about the velocity of the car is true
  • A
    Magnitude of velocity is not constant
  • B
    Both magnitude and direction of velocity change
  • C
    Velocity is directed towards the centre of the circle
  • ✓
    Magnitude of velocity is constant but direction changes
✓

Answer

Correct option: D.
Magnitude of velocity is constant but direction changes
(d) As body covers equal angle in equal time intervals. its angular velocity and hence magnitude of linear velocity is constant.
