Question: 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.
Part I: What is the magnitude of the electric force on a protein with this charge in a 1700N/C electric field?
I need help to find the magnitude of the electric force on a protein and express your answer using two significant figures.
