Question

Why as we go near to the centre of Earth our weight reduces (not mass)

Answer 1

weight=mass*gravity

here mass of any fixed object never changes

but weight changes because it is a force applied by our mass and gravity

and value of gravity changes so does our weight

Answer 2

Answer:

mass remains constant for the body, but the acceleration due to the gravity varies as we moves far away and towards the center of the Earth.

Explanation:

The weight is given as the mass multiplied by the acceleration due to the gravity 'g'.

Now,

here the mass remains constant for the body, but the acceleration due to the gravity varies as we moves far away and towards the center of the Earth.

So as we move near to the center of the earth the value of acceleration due to the gravity reduced, thereby reducing the weight of the body.
