A body of mass 10 kg is dropped to the ground from a height of 10 metre. The work done by the gravitational force is (g=9.8 ms−2)−490 J−980 J+490 J+980 J

A body of mass $10 k g$ is dropped to the ground from a height of $10$ metre. The work done by the gravitational force is $(g = 9.8 m s^{- 2})$
$- 490 J$
$- 980 J$
$+ 490 J$
$+ 980 J$
