Two charges QA = +2 C and QB = - 6 C are located on the x-axis

Two charges QA = +2 μC and QB = - 6 μC are located on the x-axis at xA= - 1 cm and xB= +2 cm respectively. Where should a third charge, QC = + 3μC, be placed on the positive x-axis so that the potential at the origin is equal to zero?

x = 5 cm

x =+2 cm

x = 3 cm

x = 4 cm

x = +1 cm
