Answer:
The electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
Step-by-step explanation:
Given;
thickness of the membrane wall, d = 14 nm = 14 x 10⁻⁹ m
potential of the membrane wall, V = 0.11 V
The electric field in the membrane wall of a living cell is calculated as;

Therefore, the electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
