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 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 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 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:

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:

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 16 mu C and -8 mu C are kept at certain distance apart , then the force if F. They are touched and again kept at the same distance , the force becomes.
