A point charge of $\displaystyle 10^{-8} C$ is placed at origin. The work done in moving a point charge $\displaystyle 2 \mu C$ from point $\displaystyle A(4,4,2) m$ to $\displaystyle B(2,2,1) m$ is $\displaystyle \_\_\_\_$ J. $\displaystyle \left(\frac{1}{4 \pi \epsilon_{\mathrm{o}}}=9 \times 10^9\right.$ in SI units)
