Work Energy And Power Question 62

Question: 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 Screening 2003]

Options:

A) W1>W2>W3

B) W1=W2=W3

C) W1<W2<W3

D) W2>W1>W3

Show Answer

Answer:

Correct Answer: B

Solution:

Gravitational force is a conservative force and work done against it is a point function i.e. does not depend on the path.
