Question

Explain why the value of g is zero at the centre of the earth

Answer 1

obiously it would be zero as the concept of gravitational force is a particle with a mass attracts another particle. gravity is the force with which earth attracts another particle. since at the centre no mass so obiously no gravity.

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.
