Weights of two bodies are 20N and 30N. If they are separated by a distance of 2 m, what is the force of gravitation acting between them?
(Take `g = 10ms^(-2)`)

What is the gravitaional force acting on 2 kg mass ? [Take g = 10ms^(-2) ]

The mass of a ball is four times the mass of another ball. When these balls are separated by a distance of 10 cm , the gravitational force between them is 6.67xx10^(-7) N . The masses of the two balls are in kg .

There are two charges +1 muC and +5muC , separated by a distance of 0.2 m in air, the ratio of forces acting in them will be:

If the masses of two bodies are quadrupled and the distance between their centres is doubled, then how many times the force of gravitation between them will be changed ?

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

The bodies of masses 40 kg and 80 kg are at a distance of 0.15 m from each other . Two force of gravitation between the bodies is 1.0 mg wt. calculate the constant of gravitation . Take g = 10 ms^(-2) .

If the distance between earth and sun is increased by 2 % , then find percentage change in gravitational force acting between them .

The force of gravitation between two bodies of mass 2 kg each separated by a distance of 2 m in vacuum is
