A particle moves in a circle of radius 5 m with constant speed and time period 2π s. The acceleration of the particle is :
15 m/s²
25 m/s²
36 m/s²
5 m/s²

Solution:

As speed of the particle is constant only centripetal acceleration will act on the object.

Centripetal Acceleration = ω²R

a c = (2π/2π)× 5= 5 m/s²
