Question
The intensity of gravitational field at a point situated at a distance 8000 km from the centre of Earth is 6.0 newton /kg. The gravitational potential at that point in newton - meter / kg will be : -
Options
A.6
B.4.8 × 107
C.8 × 105
D.4.8 × 102
Solution
Ig = 
, V= - 
,
V = Ig R = 6 × 8 × 106 = 4.8 × 107
, V= - ,V = Ig R = 6 × 8 × 106 = 4.8 × 107
