Question

A particle moves in a circle of radius 5 cm with constant speed and time period 0.2 π s. The acceleration of the particle is

(a) 15 m/s²

(b) 25 m/s²

(c) 36 m/s²

(d) 5 m/s²

Answer 1

Correct option (d) 5 m/s²

Explanation:

Here, Radius, R  =  5 cm =  5 x 10^-2 m

Time period, T  =  0.2 π s.

Centripetal acceleration
