Experimentally it is found that 12.8 {\eV} energy is required to separate a hydrogen atom into a proton and an electron. So the orbital radius of the electron in a hydrogen atom is \frac{9}{ {\x}} \times 10^{-10} {\m}. The value of the {\x} is _______ : (1 {\eV}=1.6 \times 10^{-19} {\J}, \frac{1}{4 \pi E_0}=9 \times 10^9 {\Nm}^2 \/ {\C}^2. and electronic charge =1.6 \times 10^{-19} {\C}) [6-Apr-2023 shift 2]
