Question

A car moves on a circular road. It describes equal angles about the centre in equal intervals of time. Which of the following statements 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

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

Q. A car moves on a circular road. It describes equal angles about the centre in equal intervals of time. Which of the following statements about the velocity of the car is true?

Magnitude of velocity is not constant

Both magnitude and direction of velocity change

Velocity is directed towards the centre of the circle

Magnitude of velocity is constant but direction changes
