Assume that an EM plane wave with an electric field intensity E = (3xˆ − 5zˆ) cos(3ωt − 7z − 4x) (V m−1) is incident from air on the dielectric medium μ = μ0, ε = 3.2ε0 at x > 0. Determine: i) the incident and transmission angles; ii) the reflection and transmission coeffiients; iii) The Brewster angle. How do the determined values differ for those in vacuum?

An electron is placed in a region with a 1010 V/m electric field directed in the positive x-direction. The electron escapes this region after traveling 14.0 cm. What is the kinetic energy of the electron? What is the particle's velocity? Will a proton placed at the same initial position and traveling through a similar 14.0 cm path acquire the same amount of kinetic energy? Will the proton experience the same change in velocity? Why or why not? I have seen...

Near the surface of the Earth there is an electric field of about 150 V/m which points downward. Two identical balls with mass 0.407kg are dropped from a height of 2.29m , but one of the balls is positively charged with q1 = 338?C , and the second is negatively charged with q2=-338?C . Use conservation of energy to determine the difference in the speeds of the two balls when they hit the ground. (Neglect air resistance.)
