Question

If distance between two object increase twice then force of attraction degrees ____time.(4,6)​

Answer 1

4

Given,

Distance increased twice.

Gravitational force,F=G M/r square where m and r is variable.

If r increase to twice, keeping F= constant.

F=GM M/(2r) square

GM M/r square = GM m′/4r square

m′=4m

Hence, one mass increase to four times.
