Question

what is the value of gravitational acceleration at the centre of the earth​

Answer 1

Explanation:

Recall from an earlier lesson that acceleration is the rate at which an object changes its velocity. It is the ratio of velocity change to time between any two points in an object's path. To accelerate at 9.8 m/s/s means to change the velocity by 9.8 m/s each second.

Answer 2

Answer:0(zero)

Explanation:

gravitational Acceleration due masses of body

hence at center, force is acting in all the directions.so the net acceleration becomes zero
