# An object with a mass of 7 kg is revolving around a point at a distance of 7 m. If the object is making revolutions at a frequency of 13 Hz, what is the centripetal force acting on the object?

$\text{28020 N}$

#### Explanation:

Centripetal Force is given by

"F = mr"^2 ω

"F = mr"^2 × (2 π f) color(white)(..)[∵ ω = 2 π f]

$\text{F = 7 kg"× ("7 m")^2 × 2 pi × "13 Hz ≈ 28020 N}$
