A protein molecule in an electrophoresis gel has a negative charge. The exact charge depends on the pH of the solution, but 30 excesselectrons is typical. What is the magnitude of the electric forceon a protein with this charge in a 1500 N/C electric field?

The magnitude of the electric force on a protein with this charge is

Explanation:

Given that,

Electric field = 1500 N/C

Charge = 30 e

We need to calculate the magnitude of the electric force on a protein with this charge

Using formula of electrostatic force

Where, F = force

E = electric field

q = charge

Put the value into the formula

Hence, The magnitude of the electric force on a protein with this charge is
