Question

In a region of space the electric field is given by $\vec{E} = (8 \hat{i} + 4 \hat{j} + 3 \hat{k})$ unit. The electric flux through a surface of area of 100 unit in xy plane is _____

Easy

Solution

$\begin{array}{l} ϕ_{E} = \vec{E} . \vec{A} = (8 \hat{i} + 4 \hat{j} + 3 \hat{k}) . (100 \hat{k}) unit \\ = 300 unit . \end{array}$
