Question

suppose the radius of earth becomes five times of its original radius and mass is reduced to 12.5 times of its original mass then what will happen to your weight?​

Answer 1

please mark me as brainiests i will also mark you as brainiests

The radius of the earth is twice its original radius.

To Find:

The change in our weight when the radius of the earth is twice its original radius.

Solution:

We know that F = GMm p2 is the weight of the body which is attracted towards the earth.

.. W = GMm p2 > (1) ->

If the radius of the earth becomes twice the original radius then,

→ W = GMm (2r)² = GMm 4r2 (2), comparing equation (2) with equation (1) we get,

→ W = 1/4

Hence, the weight is reduced by one fourth of its original weight.

Answer 2

Answer:

Answer: weight is inversely proportional to the square of radius. Therefore, when radius R of the earth becomes twice of its present radius, our weight become 1/4 of its present
