A body of mass 10 kg is dropped to the ground from a height of 10 metres. The work done by the gravitational force is `(g=9.8m//sec^(2))`

A

`-490` Joules

B

`+490` Joules

C

`-980` Joules

D

`+980` Joules

Text Solution

Verified by Experts

The correct Answer is:

D

As the body moves in the direction of force therefore work done by gravitational force will be positive.
`W=Fs=mgh=10xx9.8xx10=980 J`
