Suppose that the electric potential outside a living cell is higher than that inside the cell by 0.09 how much work is done by the clectric force when a sodium ion charge d e s brore the outside to the inside number units the tolerance is */-2%

Explanation:

The difference in electric potential between the inside and the outside of the cell is

The work done by the electric force to bring the ion from outside to inside is

where

q is the charge of the ion

A sodium ion, , has given off an electron: so its electric charge is

Therefore, the work done is:
