QUESTION 1 Charge +2q is placed at the origin and charge -q is placed at x = 2a. Where can a third positive charge +q be placed so that the force on it is zero? O 3.4a 6.8a O 8.6a O 9.3aQUESTION 2 Consider a square which is 1.0 m on a side. Charges are placed at the corners of the square as follows: +4.0 Cat (0, 0): +4.0 jC at (1, 1); +3.0 jCat (1, 0): -3.0 uC at (0, 1). What is the magnitude of the electric field at the square's center? 9 1.1 x 105 N/C O 1.3 x 105 N/C O 1.5 x 105 N/C O 1.7 x 10- N/C
