Formative Assignment 4 Electric fields 1. A point charge of Q2 = 5.00 /C is at the origin and a point charge of Q, = -2.00 /C is located along the x-axis at x = d. Find the net force on a third point charge Q, = 5.00 /C located along the y axis at y = d. d is an unknown variable. a) Draw a well-labeled diagram of the three charges on a Cartesian coordinate system. b) Make use of Coulomb's law and find a symbolic expression for the net force on Q1 that is, derive a formula for the net force in terms of Q2, Qa, d, and the fundamental constants c Write down the position vectors for the three charges in terms of the unit vectors. Find the two displacement vectors and their magnitude. Substitute all give info into question (b) and simplify the equation in terms of d
