Find the gravitational potential at a point on the earth surface. take mass as of earth as 5.98×10^24kg, it's radius as6.38×10^6nand g=6.67×10^-11nm^2kg^-2

Explanation:

The gravitational potential at a point on the Earth surface is given by:

where

G=6.67×10^-11Nm^2kg^-2 is the gravitational constant

M=5.98×10^24kg is the Earth's mass

R=6.38×10^6 m is the Earth's radius

Substituting the numbers into the equation, we find
