The problem is:
Find the electric field at a point midway between two charges of +30.0 x 10^-9C and +60.0 x 10^-9 C separated by a distance of 30 cm.
I used E=k (Q/r^2)
My attempt is:
E=(9x10^9)(30.0 x 10^-9C)/(.3m^2)
E=3000 N/C
E=(9x10^9)(60.0 x 10^-9 C)/(.3m^2)
E=6000 N/C
added they are 9000 N/C. I am fairly certain this is incorrect, but I do not understand the material. I really have no idea why or how to go about finding the correct answer. Please help!
