Electric Field Question

  1. 1. The problem statement, all variables and given/known data
    Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.0x10^7 N/C. What is the magnitude of the force on a calcium ion with charge +e?


    2. Relevant equations
    E = F/q > F = Eq


    3. The attempt at a solution
    Well, I thought that +e = ~1, so F = 1.0x10^7(1)
    So, F would equal 1.0x10^7, but that is not correct.

    Can anyone help me?

  3. What is +e in C? F=Eq is correct.
     
  4. Is +e the same as e-? Because 1 e- is equal to 1.6x10^-19 C, right?
    So, is that the same for +e?
