Question
What is mass of a car which is revolving around a point. The radius of the circle formed is 120 m. The speed of the rotation is 5 m/s. the centrifugal force acting on the ball is 200 N.
- 500 Kg
- 750 Kg
- 960 Kg
- 1000 Kg
Hint:
The correct answer is: 960 Kg
mass, m = ?
velocity, v = 5 m/s
radius, r = 120m
centrifugal force, Fc = 200N
Using the given formula, 
we will find the missing value,
= 960 kg
