The work done by the external force as the object makes one revolution is 47 J.
Explanation:
Given that,
Mass of the object, m = 0.5 kg
Radius of the track, r = 2.5 m
Force acting on the object, F = 3 N
Let W is the work done by the external force as the object makes one revolution. Its formula is given by :
W = 47.12 Joules
or
W = 47 J
So, the work done by the external force as the object makes one revolution is 47 J.
