Question

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

Answer 1

Answer:

Due to the normal force and gravitational force actually they canceled each other

Answer 2

Because

at that point (centre) the mass of the earth is equally distributed in all directions

so pulling equally in all directions with a net zero force as the distance from the centre decreases the acceleration due to gravity also decreases.

She really hurt me... Why'd she call me Stupid Face?

Is my face stupid? How's that even possible?

A person could be stupid, but a face, that's impossible"
