Two charges 2 C and 6 C are separated by a finite distance. If a charge of-4 C is added to each of them,the initial force of `12 xx 10^(3)` N will change to

Two equal and opposite charges separated by a finite distance is

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

The force between two charges 4C and -2C which are separated by a distance of 3km is

Two point charge +2 C and +6 C repel each other with a force of 12 N . If a charge of -4 C is given to each other of these charges , the force will now be

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 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
