A particle is moving on a circle of radius 5 m. A constant force of magnitude 10 N acts on the particle along the tangent. Find the work done by this force when particle will complete one circle.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Force F is varying because its direction is changing.
The work done
where 
is a small path length and small path length will always be along the tangent.
