Question.
Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.
Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.
Solution:
$\mathrm{F}_{\mathrm{g}}=\frac{\mathrm{GMm}}{\mathrm{R}^{2}}$
Where G is gravitational constant, M is the mass of the earth, m is the mass of the object, R
is the distance between the centre of the object and the centre of the earth radius of earth.
