Gravitational potential difference between surface of a planet and a point situated at a height of 20m above its surface is 2joule/kg. If gravitational field is uniform, then the work done in taking a 5kg body of height 4 meter above surface will be :-

Correct option is A)
The potential difference for a distance of 20m is 2joule/kg.
Now work done =m× potential difference.
Thus work done for a distance of 4m for a mass 5kg, W=204×2×5
