Question

In a uniform circular motion, the centripetal acceleration is

• A. Towards the centre of the circular path and perpendicular to the instantaneous velocity
• B. Away from the centre of the circular path and perpendicular to the instantaneous velocity
• C. A variable acceleration making $45^o$ with the instantaneous velocity
• D. A variable acceleration, parallel to the instantaneous velocity

Answer 1

Answer: (A)

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