Question

Q3 Two objects of masses ml and m2 are placed at a distance d. The force of gravitational attraction
between them is proportional to
a) mlm2/d? b) mlm2d2 c) d/mlm2 d) mlm2/d​

Answer 1

Correct Question

Two objects of masses m1 and m2 are placed at a distance d. The force of gravitational attraction between them is proportional to

a) m1m2/d² b) m1m2d² c) d/m1m2 d) m1m2/d

Solution -

Given that, two objects of masses m1 and m2 are placed at a distance 'd' apart from each other.

We have to find the gravitational force between them.

According to Law of Gravitation:

The force between two objects having mass 'm' and 'M' is directly proportional to their masses and inversely proportional to square of distance between them.

F = GMm/R²

Where, G is gravitational constant.

As per given condition,

Masses of two objects are m1 and m2. Assume that M is equal to m1 and m is equal to m2. And the distance between object m1 and object m2 is d.

So, we can write it like,

F = Gm1m2/d²

Therefore, the force of gravitational attraction between them is proportional to m1m2/d².

Option a) m1m2/d²

Answer 2

Answer:

Two object = M1 and M2

Explanation:

Correct answer is (A) M1M2/D²
