Question

Two point charges +2C and +6C repel each other with a force of 12 N. If a charge of - 2C is given to each of these charges the force will now be (A) zero (B) 8 N (attractive) (C) 8 N (repulsive) (D) None of these

On adding -2C to both, one charge becomes neutral and hence Coulomb's force equals zero.

zero

8 N (attractive)

8 N (repulsive)

None of these
