Question

Proof that gravitational acceleration is zero at the center of the earth.

Answer 1

Explanation:

At centre the value of r ( distance ) is zero so the gravity at centre is zero.

Thank you

Answer 2

Yes, the gravitational force at the earth's center is zero. ... acceleration due to gravity at the centre of the Earth is zero.

becoz The only gravity strong enough for us to feel comes from the Earth's mass, which is why we feel a downward pull on the surface. At thecenter of the Earth, the situation is different. Because Earth is nearly spherical, the gravitational forces from all the surrounding mass counteract one another.
