Question

What is the value of acceleration due to gravity at the centre of the earth
Negative b) positive c) zero d) none of the above​

Answer 1

Answer:

So, acceleration due to gravity is zero at the center of the Earth. Consider a test mass (m) taken to a distance (d) below the earth's surface, the acceleration due to gravity that point (gd) is obtained by taking the value of g in terms of density.

Explanation:

i hope this answer is right

Answer 2

Answer:

the accleration due to gravity at the centre is 0 because the earth pulls every body towards its centre. So when a body is already at the centre then there is no need to pull thr body.
