Question

What is the total flux through the two flat faces of area \[A\] for the pillbox around an infinite plane sheet?

विकल्प

• \[EA\]

• \[E \cdot (4\pi r^2)\]

• \[2EA\]

• \[E \cdot (2\pi r l)\]

Answer 1

Each of the two flat faces contributes flux \[EA\]. Adding the two contributions gives a total flux of \[2EA\].
