(01) (based on Prob 21.10) Two point charges are placed on the x-axis as follows: Charge q1 = +4.00 nC is located at x = 0.2 00 m, and charge q2 = +5.00 nC is at x = 0.300 m. What are the magnitude and direction of the total force exerted by these two charges on a negative point q3 = 6.00 nC that is placed at the origin? (Q2) (based on Prob 21.16) Three point charges are arranged along the x-axis. Charge q1 = +3.00 IttC is at the origin, and charge q2 = 5.00 ,u.C is at x = 0.200 m. Charge q3 = 8.00 ILtC. Where is q3 located ifthe net force on q1 is 7.00 N pointing in the x-direction
