A block is raised from position A to B by taking two different paths as shown in the figure. If AB = h, then

Options

A. the work done on the block is greater in case of path 1 than in case of path 2
B. the work done on the block is greater in case of path 2 than in case of path 1
C. the work done on the block is same for both paths
D. the work done cannot be determined.

Answer

C

Explanation

Work done by gravity in moving an object from one place to another depends only on the initial and final positions, not on the path taken . In both the situations, work done on the block is same i.e. . mgh
