Aprotein 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 1700 n/c electric field?
express your answer in newtons.

Electric force,

Explanation:

A protein molecule in an electrophoresis gel has a negative charge. Electric field, E = 1700 N/C

There are 30 excess electrons. The charge on 30 electrons is, q = 30e

The electric force in terms of electric field is given by :

So, the magnitude of the electric force on a protein is . Hence, this is the required solution.
