Question

If an electric field is given by $10^i + 3^j + 4^k,$ calculate the electric flux through a surface of area $10$ units lying in $y z$ plane

Open in App

Solution

$\to E = 10^i + 3^j + 4^k$
Since, we have surface area of unit $10$ lying in $Y_{2}$ plane.\perp^r $t o [l a n e$ Y_z$]
Hence, the area vector $
$\to S = 10^i$
We know that
flux $(ϕ)$ is given as
$ϕ = \int \to E \cdot \to d s$
$ϕ = \to E \cdot \to S$
$= (10^i + 3^j + 4^k) \cdot (10^i)$
$ϕ = 100 N m^{2} c^{- 1}$
