Given:
F is given as 400N
one full additional earth radius formed
To Find:
Weight of the woman=?

We know that gravitational force is inversely proportional to the square of radius.
where
is the gravitational force
is the radius square
So when radius is doubled, the force becomes one fourth of the original.
Therefore
