Two similar spheres having `+Q` and `-Q` charge are kept at a certain distance. F force acts between the two. If in the middle of two spheres, another similar sphere having `+Q` charge is kept, then it experiences a force in magnitude and direction as

Two similar spheres having +q and -q charges are kept at a certain distance. The force acts between the two is F . If in the middle of two spheres, another similar sphere having +q charge is kept,then it experience a force in magnitude and direction as

Two similar spheres having +q and -q and +4q charges are kept at a certain distance. The force acts between the two is F . If in the middle of two spheres, another similar sphere having +q charge is kept,then it experience a force in magnitude and direction as

Two point charges Q and - Q //4 are separated by a distance X . Then . force between this two charge

When two spheres having 4Q and - 2Q charge are placed at a certain distance, the force acting between them is F. Now they are connected by a conducing wire and again separated from each other. Now they are kept at a distance half of the previous one. The force acting between them is.......

Two point charges A and B, having charges +Q and -Q respectively, are placed at certain distance apart and force acting between them is F. If 25% charge of A is transferred to B, then force between the charges becomes:

If two identical spheres having charge 16muC and -8mu C are kept at certain distance apart, then the force is F. They are touched and again kept at the same distance, the force becomes

Two particles having charge Q_(1) and Q_(2) , when kept at a certain distance exert a force F on each other . If the distance between the two particles is reduced to half and the charge on each particle is doubled , the force between the particles would be

Two particles having charge Q_(1) and Q_(2) , when kept at a certain distance exert a force F on each other . If the distance between the two particles is reduced to half and the charge on each particle is doubled , the force between the particles would be
