Question

Gravitational force between two-point objects having masses m1 and m2 separated by
distance ‘r’ from their centres is
(A) Directly proportional to product of their masses and inversely proportional to
distance between their centers
(B) Directly proportional to product of their masses and is independent of distance
between the masses.
(C) Depends on distance between the masses and is independent of magnitude of masses
(D) Directly proportional to product of their masses and inversely proportional to square

________________________________

• D] Directly proportional to product of their masses and inversely proportional to square of distance between them.

________________________________

Explanation /–

According to the Universal law of gravitation /–

$f = G \times \frac{m1 \times m2}{ {r}^{2} }$

Where,

• F = Force ( Here, Gravitational force )
• r = Distance between centre of two objects.

Therefore, If we double the distance between two bodies, the gravitational force becomes one–Fourth and if we halve the distance between two bodies, then the gravitational force becomes four times.
