Answer:
Electric potential, V = 19.2 volts
Step-by-step explanation:
In this case we need to find the electric potential due to the nucleus of hydrogen at a distance of
. For this we must know the concept of electric potential. It is the work done in moving a charged particle in electric field from zero to a particular point. Its formula is given by :

q is the charge of nucleus of hydrogen i.e. proton


So, the electric potential due to the nucleus of hydrogen at a given distance is 19.2 volts. Hence, this is the required solution.
