Question

Electric field intensity at a point in between two parallel sheets with like charges of same surface charge densities $(\sigma)$ is

• A. $\frac{\sigma}{2 \varepsilon_{\text {0 }}}$
• B. $\frac{3 \sigma}{\varepsilon_{0}}$
• C. $\frac{2 \sigma}{\varepsilon_{0}}$
• D. Zero

Answer 1

Answer: (D)

Due to parallel sheets electric field is

$E =\left(\frac{\sigma}{2 \varepsilon_{ 0 }}\right)+\left(\frac{-\sigma}{2 \varepsilon_{ 0 }}\right)=0$
Because both electric fields are in opposite direction.
