q1=2.0*10^-5C. q2=8.0*10^-6C

- <-----60cm------------> + <------30cm----->

X. Y Z

B. A small test charge of +1.0 uC experiences an electric force of 6.0810^-6 N to the right.

1. Determine the electric field strength at that point.

2. Calculate the force that would be exerted on a charge of -7.2*10^-4 C located at the same point, in place of the   test charge

C. A charge of 1.2*10^-3C is fixed at each corner of a rectangle that is 30cm wide and 40 cm long. Determine the electric field and the electric potential at the center.
