Three point charges are placed on the y-axis: a charge q at y=a, a charge –2q at the origin, and a charge q at y= –a. such an arrangement is called an electric quadrupole. (a) find the magnitude and direction of the electric field at points on the positive x-axis. (b) use the binomial expansion to find an approximate expression for the electric field valid for x> > a. contrast this behavior to that of the electric field of a point charge and that of the electric field of a dipole

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
