Question

state the expression for acceleration due to gravity at depth and altitude from the earth surface

Answer 1

This is an expression for theacceleration due to gravity at thedepth 'd' below the surface of theearth. This expression showsacceleration due to gravity decreases as we move down into the earth. At the centre of the earth d = R, henceacceleration due to gravity at the centre of the earth is zero.
