Question 6

Two point charges of + 6.00 $\mu$C and + 9.00 $\mu$C are placed inside a cube of edge length 0.100 m. The net electric flux due to these charges is given by

Accepted Answer

The net electric flux due to the charges is equal to the total charge divided by the permittivity of free space. The permittivity of free space is 8.85 × 10^-12 C²/Nm². Therefore, the net electric flux is:$$\Phi_{net} = \frac{Q_{net}}{\epsilon_0} = \frac{(6.00 \mu C + 9.00 \mu C)}{8.85 imes 10^{-12} C^2/Nm^2} = 1.69 imes 10^6 Nm^2/C$$
