Question

Two point charges A and B , having charges +q and -2q respectively , are placed at certain distance

apart in free space . the force acting between them is F. 20% charge of A is transferred to B then force

between the charges becomes :

(a) 14.4F

(b) 12.2F

( c) 1.44F​

(d) 12.6F

Answer 1

Answer:

answer is C

Explanation:

hence find total charge that's is 36/25q

then forces acting kq2/r^2

=1.44F
