1.	If the masses and mutual distance between the two objects are doubled, what is the change in the gravitational force between them?
Answer» Solution :ByNewton.slaw of gravitaional ` F = (GM_(1)M_(2))/(r^(2))` Here , the massesand mutual DISTANCEBETWEEN the TWO objectsare DOUBLED ` F = (G(M_(1))(2M_(2)))/((2r)^(2)) = (4GM_(1)M_(2))/(4r^(2))` ` F = (GM_(1)M_(2))/(r^(2))` Thereis no changein the GRAVITATIONAL forcebetweenthem .
