Question

1. State the universal law of
gravitation.
2. 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:

The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. In equation form, this is F=GmMr2 F = G mM r 2 , where F is the magnitude of the gravitational force. G is the gravitational constant, given by G = 6.673 × 10−11 N·m2/kg2.
