| Back | \(Q_{enclosed}=\sum Q_i\) |
| Front | What are 2 things we can do to simplify the following equation in the context of Gaus's law around a spherically symmetric charged sphere? \(\oint E_r(r)dA?\) |
| Back | By radial symmetry, \(E_r \) takes the same value at all points, so can be re-written as \(E(r) \oint dA\), and \(\oint dA\) is simply the surface area of a sphere \(4\pi r^2\) |
