Question

A body weighs 40 kg on the surface of earth. At the centre of earth, its mass and weight respectively are:

a) 40 kg, 40 kg b) 40 kg, zero c) zero, zero d) zero, 40 kg​

Answer 1

at the centre of the earth g value is zero because radius of the is numerically equal to depth so,at the center the mass remains constant i.e 40kg but weight changes as g value becomes 0 hence weight is zero at the center

Answer 2

Answer:

Option d) is correct

Because the mass in the center of the earth is always zero as because the radius of the numerically equal to the depth.

and the weight of the body is always 40kg in all part of the universe.
