The gravitational force between two particles of masses `m_(1)` and `m_(2)` separeted by the same distance, then the gravitational force between them will be

On doubling the distance between two masses the gravitational force between them will

Assertion : The centres of two cubes of masses m_(1) and m_(2) are separated by a distance r. The gravitational force between these two cubes will be (Gm_(1)m_(2))/(r^(2)) Reason : According to Newton's law of gravitation, gravitational force between two point masses m_(1) and m_(2) separated by a distance r is (Gm_(1)m_(2))/(r^(2)) .

Assertion : The centres of two cubes of masses m_(1) and m_(2) are separated by a distance r. The gravitational force between these two cubes will be (Gm_(1)m_(2))/(r^(2)) Reason : According to Newton's law of gravitation, gravitational force between two point masses m_(1) and m_(2) separated by a distance r is (Gm_(1)m_(2))/(r^(2)) .

The gravitational force between two particles of masses m_1 and m_2 seperated by certain distance in air medium is F. If they are taken to vaccum and seperated by the same distance, then the gravitational force between them will be

If distance between the two bodies is doubled.then the gravitational force between them will become

The gravitational force between two particles separated by a distance r varies as ……………

The gravitational force between two bodies is F. If the mass of each body is doubled and the distance between them is halved , them the force between them will be
