Question 9
Two particles are placed at some distance. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the value of gravitational force between them will be

(a) $\frac{1}{4} t i m e s$
(b) $4 t i m e s$
(c) $\frac{1}{2} t i m e s$
(d) Unchanged

Open in App

Solution

(b) $4 t i m e s$

According to the formula gravitational force is equal to

$F = \frac{G M m}{d^{2}}$

If you double the mass, the force will increased by 4 times.
