Hello ✨


ĀNSWĒR ⏬⏬


we know that , In Newton's law of gravitation



$F = \frac{GMm}{{r}^{2} } ....1equation$
Here F is force is experienced by the body or an object due to earth gravitational field which is known as gravitational force. It is equal to the weight of body i.e F= mg


put value of F in equation 1

therefore


$mg = \frac{GMm}{{r}^{2} }$
here g stands for gravitational constant
M stands for mass of Earth,or
r is the radius of earth



$so, G= 6.67 \times {10}^{ - 11} Nm/ {kg}^{2} \\ \\ = M = 5.972 \times {10}^{24} kg \: \\ \\ r = 6.4 \times {10}^{6} m \\ \\ after \: putting \: it \: we \: get \: \\ g = 9.8m/ m {s}^{2}$


Hence value of g is 9.8 /ms^2
