# An object of mass 2 kg moves with a velocity of 10 ms1 round at circle of radius...

### Question

An object of mass 2 kg moves with a velocity of 10 ms1 round at circle of radius 4 m. Calculate the centripetal force on the object

A)
25 N
B)
100 N
C)
50 N
D)
40 N

### Explanation:

Centripetal force,
F = $$\frac{mv^2}{r}$$
= $$\frac{2 \times 10^2}{4}$$
= $$\frac{200}{4}$$= 50N

## Dicussion (1)

• Centripetal force,
F = $$\frac{mv^2}{r}$$
= $$\frac{2 \times 10^2}{4}$$
= $$\frac{200}{4}$$= 50N
