A particle moves in a circle of radius 5 cm with constant speed and time period 0.2 The acceleration of the particle is
15m/s2
25m/s2
36m/s2
5m/s2
As learnt in
Centripetal acceleration -
When a body is moving in a uniform circular motion, a force is responsible to change direction of its velocity.This force acts towards the centre of circle and is called centripetal force.Acceleration produced by this force is centripetal acceleration.
