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 $g = 9.8 m / s e c^{2}$

Question

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 - 9-8 m - sec-2 -

Correct option is D- - -980 -quad joules -Work done is given by-W-Fs-Where F is the force and s is the displacementAs the body moves in the direction of force- therefore work-160- done by gravitational force will be positive- W-160- - Fs-160- -mgh - 10 -times 9-8 -times 10 - 980 J -

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 $$ ( g = 9.8 m / sec^2 ) $$

Correct option is D. $$ +980 \quad joules $$
Work done is given by:
$$W=Fs$$
Where F is the force and s is the displacement
As the body moves in the direction of force, therefore work done by gravitational force will be positive.
$$ W = Fs =mgh = 10 \times 9.8 \times 10 = 980 J $$
