6. What: happens to the force between two objects, if

(i) the mass of one object is doubled?

(ii) the distance between the objects is doubled and tripled?

(iii) the masses of both objects are doubled?


Answer :

(i) If the mass of one object is doubled, the force between two objects will be doubled (increases)

As per universal law of gravitation, the force between 2 objects \( m_1 \ and \ m_2 \) is proportional to their plenty and reciprocally proportional to the sq. of the distance(R) between them.

(ii) If the distance been the objects is doubled the force between two objects will be one-fourth and if the distance will be tripled, the force will be one-ninth (1/9).

As per universal law of gravitation, the force between 2 objects \( m_1 \ and \ m_2 \) is proportional to their plenty and reciprocally proportional to the sq. of the distance(R) between them.

(iii) If the masses of both objects are doubled the force will be 4 times.

As per universal law of gravitation, the force between 2 objects \( m_1 \ and \ m_2 \) is proportional to their plenty and reciprocally proportional to the sq. of the distance(R) between them.
