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
As gravitational field is conservative in nature, work done in moving a particle from A to B does not depend upon the path followed by the body. It's equal for all the paths between any two given positions.
