Question

Two point charges of + 2 pCand + 6 °C repel
each other with a force of 12 N. If each is given
an additional charge of – 4 uC, then force will
become:
(1) 4 N (attractive) (2) 60 N (attractive)
(3) 4 N (repulsive) (4) 12 N (attractive)
​

Answer 1

Answer:

Explanation:

Initially force is 12N

12= k(6)(2)/r²

Now after giving -4 charge to each of them..new charges are -2 and 2

So F = k(2)(2)/r²

By solving both equation...

F is 4N(attractive)

As the charges are unlike in nature
