Vedclass · Answer

(B) The gravitational force is a conservative force.For a conservative force,the work done in moving a particle from one point to another is independent of the path taken.It only depends on the initial and final positions of the particle.In the given figure,all three paths $(1, 2, 3)$ start from point $A$ and end at point $B$.Since the initial and final positions are the same for all three paths,the work done along each path must be equal.Therefore,${W_1} = {W_2} = {W_3}$.

In a gravitational field,if the work done along paths $1, 2$ and $3$ is ${W_1}, {W_2}$ and ${W_3}$ respectively,then:
