Question

f g is acceleration due to gravity on the surface of the Earth and R is radius of the Earth, then the gravitational potential on the surface of the Earth is (Ans: (a) -gR) Explain the answer too

a) – gR
b) gR
c) – gR^2

d) gR^2​

Answer 1

Answer:

Explanation:

Acceleration due to gravity g = GM/R² (M- Mass of earth, R- Radius of earth)

Gravitational potential V = -GM/R ( Negative potential for attractive forces)

So V= -gR
