Problem 20 - Entrance Test

A particle is moving in a circular path of radius 3 m with a velocity of 6 m/s. Find the centripetal force acting on the particle. (m = 2 kg)

Correct: B

Using the formula for centripetal force, F = mv^2/r. Given m = 2 kg, v = 6 m/s, r = 3 m. So, F = 2 * (6)^2 / 3 = 24 N.
