Question

Two bodies of masses 100 kg and 1000 kg are at a distance 1 m apart . Calculate the gravitational field intensity and potential at the mid point of the line joining them

Answer 1

M1 = 100 kg

M2 = 1000 kg

Gravitational field intensity due to mass 100 kg is equal and opposite to 1000 kg

G x 100 / x^2 = G×10000 / (1-x)^2

100 x^2 = (1-x)^2

10x = 1-x

11x = 1

* x = 1 / 11m answer *
