Physics Question on coulombs law
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
Answer
zero
Explanation
Solution
On adding -2C to both, one charge becomes neutral and hence Coulomb's force equals zero.
