Physics Question on Capacitors and Capacitance
Two point charges +2C and +6C repel each other with a force of 12N. 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 the above
Answer
zero
Explanation
Solution
On adding −2C to both, one charge becomes neutral and hence Coulombs force equals zero.
