first Q1Q2 will be repulsive....
second q1q2 will be attractive
dbzbudokai902:
explain
in first one Q1 Q2>0 it means positive...and two negative charge or two positive multiplication can only give positive...so two charges of sign repels each other
second is q1×q2<0 in this one negative and other positive
can give smaller than zero means negative...so charges of opposite signs attract each other
hope it is clear for u frnd
thanx
