Question

pls look for the answer

Answer 1

B) 4 times is the ans.


Gravitational force=gmM/r2
= g *2m*2M/r2
=4(gmM /r2)

Thus it becomes 4 times

Plzz mark as brainliest....:-)

Answer 2

see if the particles mass are doubled, and the distance between them unchanged the gravitational force will be unchanged as gravitational force is the weakest force in the nature, which depends upon the distance of bodies.

hope this helps you.
mark it as brainleast this would be appreciated ^_^
