Question

An electric dipole consists of two opposite charges each of magnitude $1.6\times {10}^{-}19$ coulomb at separation $1Armstrong$. The diploe moment is:

• A. $1.6\times {10}^{-19}c-m$
• B. $1.6\times {10}^{-29}c-m$
• C. $3.2\times {10}^{-29}c-m$
• D. $3.2\times {10}^{-19}C-m$

Answer 1

The correct option is B $1.6\times {10}^{-29}c-m$

Dipole moment $P=qd$

So, $P=1.6\times {10}^{-19}\times {10}^{-10}=1.6\times {10}^{-29}C-m$
