Question

The electric field between two infinitely charged plates with air medium in between, in terms of the surface charge density $\sigma$ is

• A. $4\pi {\epsilon }_0$
• B. $\frac{\sigma }{4\pi {\epsilon }_0}$
• C. $\frac{\sigma }{{\epsilon }_0}$
• D. $\frac{4\pi \sigma }{{\epsilon }_0}$
• E. $\frac{\sigma }{4\pi r^2}$

Answer 1

The correct option is C $\frac{\sigma }{{\epsilon }_0}$

The electric field between two infinitely charged plates with air medium in between, in term of the surface charge density $\sigma$ is $\frac{\sigma }{{\epsilon }_0}$.
