If W1,W2 and W3 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 W1,W2 and W3 [IIT JEE 2003]
W1=W2=W3
Gravitational force is a conservative force and work done against it is a point function i.e. does not depend on the path.
