1. There are 2 charges (3 µC and 4 µC) located at (-4 cm, 0) and(4 cm, 0), respectively.
A. Determine the magnitude and direction of the electric field at(8 cm, 0).
B. Determine the magnitude and direction of the electric field at(0, 8 cm).
2. Look back to problem#1. Let the charges start infinitely faraway and infinitely far apart. They are placed at (6 cm, 0) and (0,3 cm), respectively, from their initial infinite positions.
A. Determine the electric potential due to the two charges at theorigin.
B. Determine the electric potential energy associated with thesystem, relative to their infinite initial position
