Force between two identical bar magnets whose centres are metre apart is 4.8N when their axes are in the same line. If the separation is increased to 2r metre, then the force between them is reduced

Gravitational force between two masses at a distance 'd' apart is 6N. If these masses are taken to moon and kept at same separation, then the force between them will become :

The force of attraction (A) between two objects, whose masses are fixed, varies inversely with the square of their distance of separation 9d). The force of attraction between them is 2 units when the distance is 5 cm. what is the distance between the two objects, if the attraction between them is 8 units?

Two charges are placed a certain distance apart in air. If a brass plate is introduced between them, the force between them will
