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 F_{c} = ?

Using the given formula,

we will find the missing value,

= 18.75 N
