What is the electric potential at a point distance r from a proton of charge q placed in a medium of permittivity εo?
Answer Details
The electric potential at a point distance r from a proton of charge q placed in a medium of permittivity εo is given by the formula: V = q/4πεor Here, V represents the electric potential (also known as voltage) at the point, q represents the charge of the proton, r represents the distance from the proton, and εo represents the permittivity of the medium. This formula states that the electric potential at a point is directly proportional to the charge of the proton and inversely proportional to the distance from the proton. It also depends on the permittivity of the medium, which is a measure of how much the medium can resist the formation of an electric field. Therefore, the correct answer is: q/4πεor2.
