Question

Gravitational potential difference between surface of a planet and
a point situated at a height of 20 m above its surface is 2
joule/kg If gravitational field is uniform, then the work done in
taking a 5 kg body of height 4 meter above surface will be :-
(1) 2 J (2) 20 J (3) 40 J (4) 10 J

Dear Student , h = 20 m Gravitatioanl pot
 difference = 2 j/kgVertical distance = 4 m Now potential difference for a distance of  4m for a body 5 kg is =220×4=25J/KgWork done in lifting a 5 Kg body through a height 4 m = Gravitational potential difference ×mass =25×5=2JRegards
