Question

An object with a mass of `5 kg` is revolving around a point at a distance of `3 m`. If the object is making revolutions at a frequency of `7 Hz`, what is the centripetal force acting on the object?

Answer 1

`F_c=2940*pi^2 " N"`

Explanation:

`F_c=m*omega^2*r`
`F_c=m*(2*pi*f)^2.r`
`F_c=m*4*pi^2*f^2*r`
`F_c=5*4*pi^2*7^2*3`
`F_c=2940*pi^2 " N"`
