In this part, we will be using simulation of Millikan’s famous oil drop experiment from https://www.thephysicsaviary.com/PhysicsPrograms/Labs/MillikanOilDrop.html. The idea is that we can suspend a droplet of oil in the air by balancing the gravitational force with the electrostatic (Coulomb) force. Write an algebraic expression for the gravitational force on a spherical drop of radius “r” […]
