Question

why the value of g is zero at the center of earth

Answer 1

Heya !!!

Here is Your Answer.

Question : Why is the value of g or acceleration due to gravity is zero?


We know that as the distance from the Earth decreases, the acceleration due to gravity also decreases. So, at the centre, the distance is zero. So, the acceleration due to gravity will also be zero.

Secondly, Earth is rounded shaped. So, mass of Earth is equally distributed from all sides.
We know that if equal forces act on a body from opposite directions, then net force becomes zero. So, Due to mass of Earth equally distributed from all sides makes net force zero. That's why acceleration due to gravity at the centre of Earth is zero.
