Question

For two infinitely long charged parallel sheets, the electric field at $P$ will be

• A. $\frac{\sigma}{2 x}-\frac{\sigma}{2(r-x)}$
• B. $\frac{\sigma}{2 \varepsilon_{0} x}+\frac{\sigma}{2 \pi(r-x) \varepsilon_{0}}$
• C. $\frac{\sigma}{\varepsilon_{0}}$
• D. Zero

Answer 1

Answer: (D)

$E_{N}=E_{1}-E_{2}=\frac{\sigma}{2 \varepsilon_{0}}-\frac{\sigma}{2 \varepsilon_{0}}=0$
