Question

explain why the value of g is zero at the centre of the earth ​

Answer 1

Answer:

g=GMm/r

Explanation:

r is distance between object and centre of earth, since the distance between object and centre of earth is zero at centre value of g is zero

Answer 2

Answer:

Explanation:

The acceleration due to gravity is given as

g =

GM

R2

At the centre of the Earth, the mass under

consideration is zero.

i.e. M = O

∴ g = 0

Hence, acceleration due to gravity, at the centre

of the earth, is zero.
