The self potential energy of hydrogen chloride whose dipole moment is 3.44× 10-30 C–m and separation between…..

Q:The self potential energy of hydrogen chloride whose dipole moment is 3.44× 10-30 C–m and separation between hydrogen and chlorine atoms is 1.01 × 10-10 m is
(a) 1.036 × 10-19 J
(b) 3.2 × 105 J
(c) 4.5 × 107 J
(d) 1.65 × 106 J

Ans: (a)

Dipole moment p = q × l

$\displaystyle q = \frac{p}{l}$

P.E $\displaystyle U = \frac{q^2}{4\pi \epsilon_0 l}$
