While studying the spectrum of a gas cloud in space, an astronomermagnifies a spectral linet hat results from a transition from a p stateto an s state. She finds that the line at 575.050 nm has actually splitinto three lines, with adjacent lines 4.60 * 10^-2 nm apart, indicatingthat the gas is in an external magnetic field. Ignore effects due toelectron spin. What is the strength of the external magnetic field?

Robert Millikan was an American physicist who in 1909 performed a classic experiment involving charged oil drops. Millikan adjusted the voltage applied between two metal plates in order to suspend charged drops in the resulting electric field. For a suspended drop, the electrostatic force directed up exactly balances out the weight of the drop. Millikan ultimately determined the charge on an electron and that charge is quantized. This means that charge comes in increments, discrete amounts, rather than any amount.A NEGATIVELY-charged oil drop is suspended between two plates of opposite charge by an electric field of 603 newtons per coulomb. The drop is determined to have a mass of 8.86 x 10-17 kilograms. a. What is the charge on the drop? Include units in your answer.
