Answer:
The magnitude of the electric field intensity is
Explanation:
From the question we are told that
The voltage is
The thickness of the membrane is
Generally the electric field intensity is mathematically represented as
substituting values
In an arithmetic progression, consecutive terms differ by the same value.
So, we have
which reflects the fact that the difference between P and 6 must be the same than the one between P and 14.
The equation solves to
And in fact, if you start with
every pair of consecutive terms differ by 4.
