Point charges of 6.75 µC and
−4.00 µC
are placed 0.300 m apart. (Assume the negative charge is locatedto the right of the positive charge. Include the sign of the valuein your answers.)
(a) Where can a third charge be placed so that the net force onit is zero?
m to the right of the
−4.00 µC
charge
(b) What if both charges are positive?
m to the right of the  4.00 µC charge
