Question

explain variation 'g' with depth?

Answer 1

Hey mate here is your answer

Variation of 'g' due to depth. Let us consider the earth to be spherical mass of 'M' and radius 'R'. A body of mass 'm' is placed initially on the surface and finally taken x distance deep into the earth. This expression shows that acceleration due to gravity decreases as we go deep into the earth.
