Two charges of +4.0x10^-6 C and +8.0x10^-6C are placed 2.0m apart. What is the field strength halfway between them?
= (9.0x10^9)(4.0x10^-6C) + (9.0x10^9)(8.0x10^-6C)
(2m)^2 (2m)^2
This is what I have...which part is wrong?

They are 2m apart, so the point midway between them is 1m from each, and where are theQuote:
