Q1. Two stationary positive point charges, charge 1 of magnitude 355 nC and charge 2 of magnitude 1.8 nC, are separated by a distance of .45 m. An electron is released from rest at the point midway between the two charges, and it moves next to the line linking the two charges.

What is the speed of the electron when it is 10.0 from charge 1?

Q2. A thin soap film (n = 1.33) has a uniform thickness. When white light strikes the film at normal incidence, blue light (b = 440 nm) is constructively reflected. At what angle of incidence will green light (g = 560 nm) be most strongly reflected? Imagine the film has the minimum thickness that can produce these reflections. In degrees.
