Question

suppose you are standing on a tall and if your distance from the centre of the Earth is 2r what will be your weight​

Answer 1

Explanation:

we know that,

gravitational force =GMm/(r)square

F=GMm/(r)square

Now,

F' =GMm/(2r)square

F'=GMm/(4R)square.

F=[GMm/(R)square x 1/4

F=F/4

Therefore,

so the weight at this distance will be 1/4th of the weight at surface of earth.
