I have a configuration of two charges. The first charge with a magnitude of 2C sits at point (0,1m) in a coordinate system. The second charge with a magnitude of 1C sits at the point (0,-2m).
a) What is the magnitude of the electric field, E, at the point (2m,0)?
b) What direction does the field point?
c) If I place an electron at (2m,0) what is the force that it feels?
