Question

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
• D. Magnitude of velocity is constant but direction changes

Answer 1

The correct option is D

Magnitude of velocity is constant but direction changes

As body covers equal angle in equal time intervals. its angular velocity and hence magnitude of linear velocity is constant.
