Question

1) what is the work done when a body is moved horizontally along a frictionless surface?

2) what is the work done on a body moving in a circular path?​

Answer 1

Answer:

1) The work done against the gravity when a body move horizontally along a frictionless surface is zero, as the force of gravity acts perpendicular to the direction of motion.

2) The work done on a body moving in circular path is also zero because, the body is directed towards the centre of the circular path (The body is acted upon by centripetal force).

HOPE THIS HELPS!!
