Explanation:
whenever work is done against gravity,
The amount of work done is equal to the product of weight of the body and the vertically distance through which the body is lifted .
( when m is mass and g is acceleration due to gravity).
now,
work done is lifting a body = weight of body× vertically distance
w = m × g × h
W= work done
M= mass of body
g= acceleration due to gravity
h= height through which the body is lifted.
