Q. If $W_{1},\ W_{2}$ and $W_{3}$ represent the work done in moving a particle from $A$ to $B$ along three different paths 1, 2 and 3 respectively (as shown) in the gravitational field of a point mass m, find the correct relation between $W_{1},\ W_{2}$ and $W_{3}$
A) $W_{1} > W_{2} > W_{3}$
B) $W_{1} = W_{2} = W_{3}$
C) $W_{1} < W_{2} < W_{3}$
D) $W_{2} > W_{1} > W_{3}$
Explanation
(b) Gravitational force is a conservative force and work done against it is a point function $i.e.$ does not depend on the path
