Question

Gravitational force between two objects is 10N. if masses of both objects are doubled without changing distance between them, then the gravitational force would become__________​

Answer 1

Answer:

four times

Explanation:

Mass of both the objects are doubled i.e m1 =2m1 and m2 =2m2

• ∴ F ′ = G(2m1 )(2m)2/r2

⟹F =4F

Thus gravitational force becomes 4 times.

Thus gravitational force becomes 10×4=40N

Hope it helped!!!!!

Answer 2

Answer:

the ans is 40N

Explanation:

F = Gm1 m2 divided by r^2

10 = Gm1 m2 divided by r^2 .............(1)

F^1 = G 2m1 2m2 divided by r^2 .............(2)

F^1 = 4 Gm1 m2 divided by r^2

F^1 = 4×10

= 40N Ans
