When the distance between two charged particles is doubled, theforce between them becomes

The interaction energy of London forces between two particles is proportional tomr^x, where r is the distance between the particles. The valuebof x is

Using inverse square law. If the distance between two masses  is doubled, explain the effect on the  magnitude of the force changed in terms of F.A

If the distance between two particles is halved, the gravitational force increases by:a.Three timesb.Eight timesc.Four timesd.Two times

When atoms gain or lose electrons, the charged particles that result are called
