A long string with a charge of \( \lambda \) per unit length passes through an
\( \mathrm{P} \) imaginary cube of edge a. The maximum flux of the electric field through

W the cube will be
(B) \( \frac{\sqrt{2} \lambda a}{\varepsilon_{0}} \)
(A) \( \frac{\lambda a}{\varepsilon_{0}} \)
(D) \( \frac{\sqrt{3} \lambda a}{\varepsilon_{0}} \)
