Question

a 0.5 kg mass is rotated in a horizontal circle of radius 20cm .if it's angular speed is 0.8 radius the centripetal force acting on it is
​

Answer 1

Answer:

Calculate the centripetal force acting on it, if its angular speed of revolution is 0.8 rad /s. Given: Mass of a body = m = 0.5 kg, radius of circular path = r = 20cm = 0.2 m, Angular speed = ω = 0.8 rad/s, ... Ans: Centripetal force = 0.064 N acting radially inward.
