Cocaine selectively blocks sodium channels which is the mechanism that leads to local anesthetic effects.
Voltage gated sodium channels play very important roles in the body as they are responsible for action initiation and propagation in excitable cells, such as nerves, muscles and neuroendocrine cells. Like other sodium ion channels blockers such as lidocaine, Cocaine selectively blocks sodium ion channels which denies entry of sodium ions in the cell, thus leading to local anesthetic effects.

The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:
(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.
(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.
In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
