Question

when a body is raised to a height h the work against the gravitational force would be w=​

Answer 1

Explanation:

When a body is raised to a height h,it moves opposite to the direction of gravitational force on it.Therefore,

(a)Work done by applied force is positive since the body moves in the direction of applied force.

(b)Work done by gravitational force is negative.

Answer 2

When a body is raised to a height "h" the work against the gravitational force is equal to " mgh "
