Question

A particle revolves round a circular path with a uniform speed. The centripetal acceleration of the particle is:

• A. Along the circumference of the circle.
• B. Along the tangent
• C. Along the radius
• D. Zero.

Answer 1

The correct option is A Along the circumference of the circle.

The acceleration due to the particle moves in a circular path is of two types-tangential acceleration and centripetal acceleration. In the case of tangential acceleration, the velocity of a particle changes, and for uniform velocity, the value for tangential acceleration becomes zero.
