W = FS cos xsince centripetal force always acts perpendicular to displacement, x= 900 , and cos 900 = 0So work done is also zero
Adarsh
As the direction of centripetal force and direction of displacement of particle is perpendicular the done by centripetal force will be zero
Nicho priyatham
w=∫F.dx in case of centripetal force F is perpendicular to dx(small displacement) so integral becomes zero
please approve

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same

the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
