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 .
Options
- AW 1 > W 2 > W 3
- BW 1 = W 2 = W 3
- CW 1 < W 2 < W 3
- DW 2 > W 1 > W 3
Correct answer
B. W 1 = W 2 = W 3
Step-by-step solution
Gravitational field is a conservative force field. In a conservative force field work done is path independent
