Question

If value of acceleration due to gravity at the earth surface is 10m/s^2 its valie at centre of earth

Answer 1

The acceleration due to gravity depends on the mass of the body, the distance from the center of mass, and a constant G, which is called the "universal gravitational constant". Its value is = 6.673 x 10-11 N. m2/kg2. The acceleration due to gravity on the surface of the moon is 1.620 m/s2.
