In a region of space, the electric field is given by $\vec{E} = 8 \hat{i} + 4 \hat{j} + 3 \hat{k} .$ The electric flux through a surface of area of 100 units in $x$ - $y$ plane is

Options:

Answer:

Solution:

Here, $\vec{E} = 8 \hat{i}$ $+ 4 \hat{j} + 3 \hat{k}$

$\vec{S} = 100 \hat{k}$

(direction of the area is perpendicular to $x$ - $y$ plane)

$ϕ = \vec{E}$ ⋅ $\vec{S} =$ $(8 \hat{i} + 4 \hat{j} + 3 \hat{k}) \cdot 100 \hat{k}$

$= 300 units$
