Question

please tell me the answer​

Answer 1

Answer:

Work done by the force of gravity on an object depends only on vertical displacement. Vertical displacement is given by the difference in the initial and final positions/heights of the object, which is zero.

Work done by gravity is given by the expression,

W= m g h

Where,

h= Vertical displacement = 0

W = m g — 0 = 0 J

Therefore, the work done by gravity on the given object is zero joule.
