Question
The mass of a cycle is 30 Kg.The cycle is revolving around a point. The radius of the circle formed is 40 m. The speed of the rotation is 5 m/s. the centrifugal force acting on the ball is ______
- 20 N
- 48 N
- 18.75 N
- 25 N
Hint:
The correct answer is: 18.75 N
mass, m = 30kg
velocity, v = 5 m/s
radius, r = 40m
centrifugal force Fc = ?
Using the given formula, 
we will find the missing value,
= 18.75 N
