Question

An object with a mass of `4 kg` is revolving around a point at a distance of `2 m`. If the object is making revolutions at a frequency of `5 Hz`, what is the centripetal force acting on the object?

Answer 1

`=7887.68N`

Explanation:

Given

• `m->"Mass of the object"= 4kg`
• `r->"Radius of circular path"=2m`
• `n->"Frequency of revolution"=5Hz`

• `w->"Angular velocity"=2pin`

• We know centripetal force

• `F_c=mxxw^2xxr==4pi^2n^2xxmxxr`

`=4*3.14^2*5^2*4*2=7887.68N`
