Question

A particle moves in a circle of radius 25 CM at 2 Revolution per second the acceleration of the particle is in metre per second square is

Answer 1

2 rev/sec means → ω = 2π × 2 rad/sec
Use the formula of Acceleration a = r ω2
where r = 0.25 cm
On substituting and calculating, we get
Acceleration a = 4π2 m/s2 (2 is square)

Answer 2
