Phys 112 Spring 2022 Homework #3 Due Wednesday, January 26th 1. Draw electric fields lines for a simple model of a water molecule (H20). Assume the Hydrogen atoms each carry a negative charge -q, and the Oxygen atom carries a positive charge of 2*q, and the three atoms are in a triangle formation. Include some space between each charge, and indicate the electric field at locations inside the molecule as well. (No calculations necessary, just approximate diagrams and only consider a 2D plane.)
