Question

Find the value of acceleration
due to gravity
gravity at the surface of earth
(M=6×10²⁴kg R=6400 km)​

Answer 1

Answer:

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.

Answer 2

Explanation:

The acceleration due to gravity on any planet or surface can be calculated as :

g=\dfrac{GM}{R^2}g=

R

G=\dfrac{9.774 \times (64\times 10^5)^2}{6\times 10^{24}}G=
