Four charges, qa, qb, qa, and qd are fixed at the corners of a square. A charge q that is free to move located at the exact center of the square. Classify the scenarios described according to the force that would be exerted on the center charge q. Assume in each case that q is a positive charge. Do not assume that the fixed charges have equal magnitudes unless the scenario defines such an equality. qa Яс q %b Force is zero Force is to the left Force is to the right Force is undetermined

When an electromagnetic wave is reflected at normal incidence on a perfectly conducting surface, the electric fieldvector of the reflected wave at the reflecting surface is the negative of that of the incident wave.a) Explain why this should be so.b) Show that the superposition of the incident and reflected waves results in a standing wave.c) What is the relationship between the magnetic field vector of the incident and reflected waves at the reflectingsurface?
