Question

A body of mass 0.2 kg is revolving on a circular path of diameter 20 m at the rate of 5 revolutions
m 15.7 seconds Calculate the centripetal force acnng on the body. What is its direction​

Answer 1

Answer:

Given:-

Mass = 0.2kg

Diameter of a circle = 20m

Radius = 20/2 = 10m

Speed = distance/time = 5/15.7 = 0.318471m/s

To find:-

Centripetal force

By applying, Fc = mv^2/r

= 0.2×0.318471/10

= 0.2×0.101423777841/10

= 0.202847555682/10

= 0.020847555682N.
