Two balls carrying charges `+ 7 muC` and `-5 mu C` attract each other with a force F. If a charge `-2 mu C` is added to both, the force between them will be :-

Two small balls carrying charges +9 mu C" and -4 mu C attract each other with a force "F" .If a charge of -5 mu C is added to each one of them,then the force between the balls would become

Two point charges +6 mu C and +16 mu C repel each other with a force of 120N. If a charge of -8 mu C is added to each of them, then force between them will becomes

Two point charges +10 muC and +20 muC repel each other with a force of 100N. If a charge of-2 muC is added to each charge, then force between them will become

Two point charges +3 muC and +8muC repel each other with a force of 40 N . If a charge of -5 muC is added to each of them, then the force between them will become

Two point charge +2 C and +6 C repel each other with a force of 12 N . If a charge of -2 C is given to each other of these charges , the force will now be

Two small identical spheres having charges +10 muC and - 90muC attract each other with a force of F newton . If they are kept in contant and then separated by the same distance, the new force between them is -

Two point charges of +3muC and +4muC repel each other with a force of 10 N. If each is given an additional charge of -6muC , the new force is
