Explore what happens when charge q is finite through examples q2 > q1 > 0. Learn about inducing charge p1 at point P and finding polarizability α. Dive into techniques like neutralizing metal ball and tape, charging by induction, and mathematical tools like Trig Functions, Derivatives, Integration, and Change of Variable.
