Question

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface

Answer 1

Answer:

F=GMm/R^2

Explanation:

mass of Earth=M. mass of object=m. distance between the earth and object= radius of Earth=R. therefore,force,F=GMm/R^2

Answer 2

Consider F is the force of attraction between an object on the surface of earth and earth.

Also consider ‘m’ is the mass of the object on the surface of earth and ‘Me’ is the mass of earth.

Therefore the formula for magnitude of the gravitational force between the earth and an object on the surface is given as

G = GM1m2 / r²
