Question

The acceleration due to gravity at a height (1/20)th the radius of
-2 the Earth above the Earth’s surface is 9 m s . Its value at a point at
an equal distance below the surface of the Earth is
(a) 0 (b) 9 m s-2
(c) 9.8 m s-2 (d) 9.5 m s-2

Answer 1

the value of acceleration due to gravity below the surface of the earth at a point on equal distance will be zero.
because the value of acceleration due to gravity decreases as we go deep inside the earth.
