The electrostatic force between the two charges acts along the line joining the two charges. The force is repulsive if charges are similar in nature ( q1<\/sub> q2<\/sub> > 0 ),whereas the force is attractive if the charges are dissimilar in nature (q1<\/sub> q2<\/sub> < 0 ).<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
