Question

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

Answer 1

Answer:

G*M1 * M2 / r^2

Explanation:

M1 = mass of earth

M2 = mass of object

r = distance between them

G = gravitational constant

Answer 2

Answer:

mg

Explanation:

F= GMm /r^2

M = mass of earth

m = mass of object

r = radius of earth

G = gravitational constant

F= m g where g = GM/r^2
