What is the magnitude of the force on a calcium ion

[robera1]

Homework Statement

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?

Homework Equations

E = F/q > F = Eq

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?

What is +e in C? F=Eq is correct.

Is +e the same as e-? Because 1 e- is equal to 1.6x10^-19 C, right?
So, is that the same for +e?
