Question

the value of g at the centre of the earth is_​

Answer 1

$\huge\sf\red{Required~Answer}$

• The value of g at the centre of the earth is zero.

Explanation :-

According to Newton's second law of motion,

F = mg

Force will be zero. So, the value of g will also be zero.

$\bold{Note~\mapsto~Mass~cannot~be~zero.}$

• Acceleration due to gravity of earth is maximum at the poles.
• Its value decreases when we go deep inside the mines. But its expected that it should increase.
• $\mapsto$ The reason is that The mass of the earth, as we go deep inside the mine decreases by the cube of radius whereas the distance of the body from the centre of the earth decreases by square of radius. So, on the whole acceleration due to gravity decreases.

Acceleration due to gravity :- Its value is 9.8 ${m/s}^{2}$
