Question

Two infinite plane parallel sheets, separated by a distance $d$ have equal and opposite uniform charge densities $\sigma$. Electric field at a point between the sheets is

• A. $\frac{\sigma }{{2\epsilon }_0}$
• B. $\frac{\sigma }{{\epsilon }_0}$
• C. zero
• D. depends on the location of the point

Answer 1

Answer: (B)

$\frac{\sigma }{{\epsilon }_0}$

Two infinite plane parallel sheets separated by a distance $=d$ charge densities $=\sigma$

Electric field using Gauss law $=\frac{\sigma }{{\epsilon }_0}$ (electric field is in independent of the distance between two parallel sheets).
