Point charges of 5.50 µC and −2.00 µC are placed 0.150 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 −2.00 µC charge


(b) What if both charges are positive?
________________m to the right of the 2.00 µC charge

Please explain the basic math in the end that involves factoring as well. Thank you!
