PHY 2202 General Physics II Name: Homework 1-2 “Fields and Potentials” Due: 5:15 P.M. on Tuesday, September 4, 2018. 1. For three given electric charges (see the diagram below), calculate the total electric potential in points A and B using the superposition principle. Give the answer in terms of Q and R, for ke = 1 a.u. (arbitrary unit system). First, define the reference frame (x-axis with origin). Then write the equation for the electric potential V (x) in chosen reference frame. Finally, calculate the electric potential in points A and B. 2. For three given electric charges (see the diagram below), determine the direction and calculate the total electric field strength in points A and B using the superposition principle. Give the answer in terms of Q and R, for ke = 1 a.u. (arbitrary unit system). Using the results of the previous problem, derive the equation for the electric field vector E~ (x). Then calculate the component of the the vector E~ (x) in given points A and B. Your...
