Answer:
ans is zero
Explanation:
for pulling u require force ..in this case gravitational force i.e. weight is acting downward and u have to push a body in translation motion so angle between force and displacement is 90 °
As work done is equal to dot product of force and displacement so cos theta is cos 90° which is equal to zero
It means work done is zero
work done= change in K.E
if initially body is rest then energy stored in body is zero joule
