two point charges are 10.0 cm apart and have chargeso of 2.0 uC (micro)and -2 uC, respectively. What is the magnitude of the electric field at the midpoint between the two charges?
i think i know how to do it:
both E1 and E2 go in the same direction
E1=0.72 * 10^7 and E2 = 0.72 * 10^7
then you add
and you get
1.44 * 10^7
is that correct?

Where did you get .72 from?
