Question

For a dipole, the value of each charge is ${10}^{-10}statcoulomb$ and separation is $1A^0$, then its dipole moment is :

• A. $1debye$
• B. $2debye$
• C. ${10}^{-3}debye$
• D. $3\times {10}^{-20}debye$

Answer 1

Answer: (A)

$1debye$

Given,

$q={10}^{-10}statcoulomb$

$d=1\times {10}^{-10}={10}^{-8}cm$

Dipole moment,

$P=qd={10}^{-10}\times {10}^{-8}={10}^{-18}esucm$

$P=1debye$

The correct option is A.
