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

Options

(a) 15 m/s²
(b) 25 m/s²
(c) 36 m/s²
(d) 5 m/s²

Correct Answer:

5 m/s²

Explanation:

Centripetal acceleration aᵥ = 𝜔²r
= ( 2π / T)² r

= (2π / 0.2π)² x 5 x 10⁻²

= 5 m/s²
