Force of attraction between two objects.
F = \(\frac{Gm_1m_2}{r^2}\)
where m1, m2 = masses of the objects
r = Distance between the objects.
G = Gravitational constant.
(i) If mass of one object is doubled, then the new force
∴ force becomes double.
(ii) If the distance between the objects is tripled, then new force
∴ force becomes one-ninth.
iii) If masses of both objects are doubled, then new force.
i.e. force becomes four times.
