Massachusetts Institute of Technology Department of Physics Physics 8.022 - Fall 2002 Assignment #1 Introduction and Review Coulomb's Law, Superposition, Electric Fields Reading Handout #1, Purcell Chapter 1. Problem Set #1 Work on all problems. Not all problems receive equal points. Total points for this set is 100. z (10 points) [1] A force is acting on a particle which is initially at the origin of the plane. We transport the particle on a square path defined by the points (0,0), (1,0),(1,1),(0,1) in the counterclockwise direction. A is a positive constant. { What are the units of A? { How much work does the force do when the partilce travels around the path? { Suppose that the particle is released at (1,1) and that only the force given is acting on it. The particle is not constrained to move along the square path considered initially. Give a qualitative description of its motion. Will it ever reach the origin? (assume that no other
