The product of magnitude of either charge and the distance between the two charges is termed as dipole moment.

The dipole moment is given as:

\(p = Ql\)

Here, p is the dipole moment, Q is the charge and l is distance between the two equal and opposite charges.

The distance between the two charges is,\(l = 0.53 \times {10^{ - 10}}\;{\rm{m}}\).

The magnitude of charge is, \(q = 1.6 \times {10^{ - 19}}\;{\rm{C}}\)

The relation to find dipole momentis given by,

\(p = q \times l\)

Substitute the values in the above expression.

\(\begin{aligned}p &= \left( {1.6 \times {{10}^{ - 19}}\;{\rm{C}}} \right)\left( {0.53 \times {{10}^{ - 10}}\;{\rm{m}}} \right)\\p &\approx 8.5 \times {10^{ - 30}}\;{\rm{C}} \cdot {\rm{m}}\end{aligned}\)

Thus, the dipole moment is \(8.5 \times {10^{ - 30}}\;{\rm{C}} \cdot {\rm{m}}\).
