Two point charges A and B, having charges +Q and –Q respectively, are placed at certain distance apart and force acting between them is F. If 25% charge of A is transferred to B, then force between the charges becomes :
(1) $F$
(2) $9F\over16$
(3) $16F\over9$
(4) $4F\over3$
(1) $F$
(2) $9F\over16$
(3) $16F\over9$
(4) $4F\over3$
