Question:

An electron and a proton held 1 Å apart form an electric dipole. The electric dipole moment of the dipole is:

Options:

$1.6 × 10^{-29} Cm$

$1.6 × 10^{-19} Cm$

$3.2 × 10^{-19} Cm$

$3.2 × 10^{-29} Cm$

Correct Answer:

$1.6 × 10^{-29} Cm$

Explanation:

The correct answer is Option (1) → $1.6 × 10^{-29} Cm$

The electric dipole moment, p is

$p=q×d$

$⇒p=(1.6×10^{-19}C)×(1×10^{-10})m$

$=1.6 × 10^{-29} Cm$
