Consider $E = 3 \times 1 0^{3} \hat{i}$ (N/C). What is the flux through the square of $10$ cm side, if the normal of its plane makes a $6 0^{\circ}$ angle with the X axis?

Answer:

Solution:

$ϕ = ES cos θ = 3 \times 1 0^{3} \times (10 \times 1 0^{- 2})^{2} \times cos 6 0^{\circ} = 3 \times 1 0^{3} \times 1 0^{- 2} \times \frac{1}{2} = 15$ Nm $^{2}$ /C
