Answer» tion: . If the mass of each BODY is doubled and distance between them is HALVED then the force between them will be : MEDIUMHelp best friendStudy laterANSWERGivenF g = R 2 G×m 1 ×m 1 Doubring both masses and HALVING distance.F g′ =G× ( 2R ) 2 2M 1 ×2m 2 ∴ F g′ = 41 ×R 2 G×4×m 1 ×m 2 ∴ F g′ = R 2 G×m 1 ×m 1 ×16∴ F g′ =16 F g |
