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:

F=GMm/r^2

Explanation:

According to Newton's Gravitational law

F is directly proportional to M×m

F is inversely proportional to 1/r^2

so,

F is proportional to Mm/r^2

so,

F=GMm/r^2

G is gravitational constant and value is 6.673/10^11 Nm^2/kg^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
