Help finding the voltage in a uniform E-field

[elowe93]

Homework Statement

Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. What is the voltage across an 8.67-nm-thick membrane if the electric field strength across it is 9.16 MV/m? You may assume a uniform E-field.

Homework Equations

E=-Vd

The Attempt at a Solution

.00912V/m=-V/(8.67e-9m) =7.9e-11 V

correction****

sorry i ment that for my answer i got -9.24e6 V/m. i was looking at the wrong thing.

Didn't you just post this exact same question?

Maybe this isn't necessary as it's 3 threads down, but:

Don't do this man. Is the one thread not good enough?
