In a region, the intensity of an electric field is given by $\mathrm{E}=2\hat{\mathrm{i}}+3\hat{\mathrm{j}}+\hat{\mathrm{k}} \mathrm{in} {\mathrm{NC}}^{-1}$. The electric flux through a surface $\mathrm{S}=10\hat{\mathrm{i}}{\mathrm{m}}^2$ in the region is:

• A

  5 Nm²C^-1

• B

  10 Nm²C^-1

• C

  15 Nm²C^-1

• D

  20 Nm²C^-1
