Point charges of 6.50 μC and −2.25 μC are placed 0.350 m apart. (Assume the negative charge is located to the right of the positive charge. Include the sign of the value in your answers.) (a) Where can a third charge be placed so that the net force on it is zero? m to the right of the −2.25 μC charge (b) What if both charges are positive? m to the right of the 2.25 μC charge
