A positively-charged semi-circular wire (radius R) has a uniform charge density 2. Determine the electric field at the center of the semi-circle using the following method: 1. Divide the wire into at least 6 point-like charges 2. Find a symbolic expression for the electric field at the center of the semi-circle due to each of these point-like charges. 3. Add together the electric field due to each of these six charges. 4. Make sense of both the magnitude and the direction of your electric field.
