Question

In uniform circular motion, the centripetal acceleration is:

• A. towards the centre of the circular path and perpendicular to the instantaneous velocity
• B. a constant acceleration
• C. away from the centre of the circular path and perpendicular to the instantaneous velocity
• D. a variable acceleration making ${45}^o$ with the instantaneous velocity
• E. A variable acceleration, parallel to the instantaneous velocity

Answer 1

The correct option is A towards the centre of the circular path and perpendicular to the instantaneous velocity

In uniform circular motion, the centripetal acceleration is towards the centre of the circular path and perpendicular to the instantaneous velocity.
