When three particles each having a positive charge ' q ' are placed at the three vertices of an equilateral triangle, then the electrostatic force between any two particles is F . If a fourth particle of charge ' 3q ' is placed at the midpoint of one of the sides of the triangle, then the net electrostatic force on the fourth particle due to the remaining three particles is
