For this, we need the formula: V = k q / r where k is the Coulombs law constant = 9 x 10^9 N q is the charge of the hydrogen nucleus (proton) = <span>1.6 x 10^-19 C</span> r is the distance Simply plug in the values and solve for V
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.
