Question

What happens to the force between two objects if
a) the mass of one object is doubled?
b) the distance between the objects is doubled and tripled?
c) the masses of both objects are doubled?​

Answer 1

Answer:

a) force becomes double

b) when distance is doubled

then force becomes one forth

when distance is tripled

then force becomes 1/9

c) force becomes 4 times the first

Answer 2

Answer:

since, F = GMm/d^2

(a) If mass of one object is doubled,

F1 = G × 2M × m / d^2

F1 = GMm/d^2 × 2

F1 = F×2

(b) Similarly from (a) if distance is doubled, Force becomes 1/4 times the original force.

and if distance is tripled, Force becomes 1/9 times the original force.

(c) If the mass of both the objects is doubled, the force becomes 4 time it's original force.
