Question

derivation of acceleration due to gravity of altitude​

Answer 1

Answer:

g=(GMm) /r2

Explanation:

F=mg and F=GMm

R2

m and m gets cancelled so we get the answer

Hope it helped you

Answer 2

Answer :-

According to the gravitational law

$\sf F = \frac{GMm}{R^2}$ - i

According to Newton's second law of motion -

F = ma - ii

From equation i and ii :-

$\sf ma = \frac{GMm}{R^2}$

$\sf a = \frac{GM}{R^2}$

This a is known as acceleration due to gravity.

$\boxed{\sf a = g = \frac{GM}{R^2}}$
