Question

A point charge Q is placed at the corner of a square plate of side a then the flux through the square plate is -

• A. $\frac{Q}{8 \in_{0}}$
• B. $\frac{Q}{4 \in_{0}}$
• C. $\frac{Q}{\in_{0}}$
• D. Zero

Answer 1

Answer: (D)

Zero

Answer 2

The electric field due to Q at any point of square plate will be along the plane of square therefore angle between electric field and area vector of plate is 90⁰. \ f = 0
