Question

If W1, W2 and W3 represents 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.

• A. W1 > W2 > W3
• B. W1 = W2 = W3
• C. W1 < W2 < W3
• D. W2 > W1 > W3

Answer 1

The correct option is B W1 = W2 = W3

Gravitational field is conservative in nature hence the work done does not depend on the path followed but only on initial and final positions
