Question
A protein molecule in an electrophoresis gel has a negative charge. The exact charge depends on the $\mathrm{pH}$ of the solution, but 30 excess electrons is typical. What is the magnitude of the electric force on a protein with this charge in a $1500 \mathrm{N} / \mathrm{C}$ electric field?
Step 1
Step 1: The force experienced by a charged particle in an electric field is given by the formula: \[ F = qE \] where \( F \) is the force, \( q \) is the charge of the particle, and \( E \) is the electric field strength. Show more…

A protein molecule in an electrophoresis gel has a negative charge. The exact charge depends on the pH of the solution, but 30 excess electrons is typical. What is the magnitude of the electric force on a protein with this charge in a 1300 N/C electric field? Express your answer using two significant figures. F=____N
An unknown charge sits on a conducting solid sphere of radius 10 $\mathrm{cm} .$ If the electric field 15 $\mathrm{cm}$ from the center of the sphere has the magnitude $3.0 \times 10^{3} \mathrm{N} / \mathrm{C}$ and is directed radially in- ward, what is the net charge on the sphere?
Suppose that a molecular ion with charge $-10 e$ is embedded within the 5.0 -nm-thick cell membrane of a cell with membrane potential $-70 \mathrm{mV}$. What is the electric force on the molecule?
