Question

calculate the depth of the earth from the surface of earth the acceleration due to gravity become zero​

Answer 1

$\huge{\purple{\underline{\underline{\bf{\pink{Answer:-}}}}}}$

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:

Function of g with respect to height from the ground is

g

h

=g(1−

R

2h

) for h < So as 'h' increases, the acclelration due to gravity decreases.

Function of g with respect to depth from the surface is

g

r

=g(1−

R

x

) x is the distance of the point from the surface of the earth.

As the depth increases, the value of g also decreases.

At the equator ], the net gravitational force is = Actual gravitational force - centrifugal force.

At the poles, the centrifugal force is zero and highest at the equator.
