Question

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

• A. $\frac{\sigma }{2{\epsilon }_{\text{0 }}}$
• B. $\frac{3\sigma }{{\epsilon }_0}$
• C. $\frac{2\sigma }{{\epsilon }_0}$
• D. Zero

Answer 1

Answer: (D)

Due to parallel sheets electric field is

$E=\left(\frac{\sigma }{2{\epsilon }_0}\right)+\left(\frac{-\sigma }{2{\epsilon }_0}\right)=0$
Because both electric fields are in opposite direction.
