Question

An electron is circulating around the nucleus of H-atom in a circular orbit of radius 5.3 x 10¹¹m. Calculate the electric potential energy of the atom in eV.

Answer 1

Hey dear,

◆ Answer -

E = -27.17 eV

● Explanation -

# Given -

r = 5.3×10^-11 m

e = 1.6×10^-19 C

# Solution -

Electric potential energy of H-atom is calculated by -

E = k.q1.q2/r

E = -ke^2 / r

E = -9×10^9 × (1.6×10^-19)^2 / (5.3×10^-11)

E = -4.347×10^-18 J

E = -27.17 eV

Therefore, electric potential energy of H-atom is -27.17 eV.

Hope this helped you. Thank for asking..
