Chapter 17, Problem 28P

To determine

Dipole moment of an electron and proton if they are at rest.

Answer to Problem 28P

The answer is $8.5\times {10}^{-30}C\cdot m$ .

Explanation of Solution

Given:

Distance is $0.53\times {10}^{-10}m$

Formula used:

It is known that $p=qd$ , here $q$ is the charge on an electron $1.60\times {10}^{-19}C$ and $d$ is distance.

Calculation:

The product of the magnitude of one of the charges times the separation distance is known as dipole moment.

By using the expression $p=qd$

  $\begin{array}{l}=\left(1.60\times {10}^{-19}C\right)\left(0.53\times {10}^{-10}m\right)\\ =8.5\times {10}^{-30}C\cdot m\end{array}$

Conclusion:

The required value is $8.5\times {10}^{-30}C\cdot m$ .
