In a hydrogen atom, the electron and proton are bound at a distance of about 0.53 Å.
(a) Estimate the potential energy of the system in eV, taking the zero of the potential energy at infinite separation of the electron from proton.

Potential energy,
`E_(P) = 1/(4pi epsilon_0) cdot (q_(1)q_(2))/r`
`=((9xx10^(9))xx(-1.6xx10^(-19))xx(1.6xx10^(-19)))/(0.53xx10^(-10)xx1.6xx10^(-19))eV`
`=-27.17 eV`
