Two point charges are placed on the x axis The first charge q1q1q 1 12 00 nCnC is placed a distance 15 0 mm from the origin along the positive x axis the second charge q2q2q 2 4 00 nCnC is placed a distance 9 00 mm from the origin along the negative x axis An unknown additional charge q3q3q 3 is now placed at point B located at coordinates 0 mm 13 0 mm Find the magnitude and sign of q3q3q 3 needed to make the total electric field at point A equal to zero
