. Charge q1= 1.80*10-8 C is placed at the origin O. Charge q2 =-7.20*10-8 C is placed at point A ( x =0.180 m) as shown in thefigures. a.
A charge q3 = 2.5 *10^-8 C is placed at point B ( x = 0.0900 m)as shown in fig.a. Determine the net force F3 exerted on charge q3by q1 and q2. Give your answer unit vector notation. b. The chargeq3 is now placed at point C ( x = 0.270 m) as shown in fig.b.Determine the net force F3 exerted on charge q3 by q1 and q2. Giveyour answer unit vector notation. c. Find the coordinate xD of apoint D on the negative x-axis for which of the net force F3exerted on q3 by q2 and q1 is zero. Use fig.c. q1 q 3 q2 x fig.a OB A.
