Questions from David Sang and Graham Jones Solutions for Chapter: Coulomb's Law, Exercise 3: Questions with Hints & Solutions
(a) What is the electrical potential energy of a charge of $+1 \mathrm{C}$ placed at each of the points $\mathrm{A}$, $\mathrm{B}, \mathrm{C}, \mathrm{D}$ between the charged, parallel plates shown in Figure $22.15 ?$
(b) What would be the potential energy of $\mathrm{a}+2 \mathrm{C}$ charge at each of these points? (C is halfway between $\mathrm{A}$ and $\mathrm{B}, \mathrm{D}$ is halfway between $\mathrm{C}$ and B.)
A Van de Graaff generator has a spherical dome of radius $10 \mathrm{~cm}$. It is charged up to a potential of $100000 \mathrm{~V}(100 \mathrm{kV}) .$ How much charge is stored on the dome? What is the potential at a distance of $20 \mathrm{~cm}$ from the dome?
