1. The problem statement, all variables and given/known data Two point charges of +30μC and -9μC are separated by a distance of 20.0 cm. What is the intensity of electric field E midway between these two charges? 2. Relevant equations force electric= kQq/ r^2 Electric field= force elctric /q = k X Q / r^2 3. The attempt at a solution I tried finding the electric field intensity for both point chrages at 10 cm and tried adding them together but that didn't work..
