Question

derive an expression for acceleration due to gravity​

Answer 1

Answer:

Acceleration Due to Gravity (g)

Symbol g

Dimensional Formula M0L1T-2

SI Unit ms-2

Formula g = GM/r2

Explanation:

please mark me as brainiest.

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.

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