1) You are given four identical metal spheres with the following charges: +4q, +3q, +1q, -4q. Each sphere can be placed in any of the circles in the figure below.
a) If they were arranged from left to right in the order above, what would be the electric field at point P?
b) What arrangement would give the highest (magnitude) electric field at point P?
c) What is the magnitude of the electric field at point P in the arrangement you selected in part a?
d) What arrangement would give the highest (most positive) electric potential at point P?
e) What is the electric potential at point P in the arrangement you selected in part d?
f) If you were to touch all four spheres together, and then separate them, what would the charge on each be?
