Two point charges, -10nC and +18nC are held fixed at a distance of 0.55m apart. Assume that both charges lie on the x-axis, for the -10nC x=0 and for the +18nC charge x=0.55m.
Where can a +20nC charge be placed so that the net force on it is zero?
Where can a -20nC charge be placed so that the net force on it is zero?
