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. What is the magnitude of the electric force on a protein with the 30 excess electrons in a 1540 N/C electric field

    Answer:

    7.401 * 10^(-15) N

    Explanation:

    30 electrons will have a charge:

    30 * -1.6022 * 10^(-19) C

    = – 4.806 * 10^(-18) C

    The relationship between electric field and electric force is:

    E = F/q

    This means that force, F, is

    |F| = |E|*|q|

    |F| = |1540| * |-4.806 * 10^(-18)|

    |F| = |-7401.24 * 10^(-18)|

    |F| = 7.401 * 10^(-15) N
