MCQ
Two infinitely long parallel conducting plates having surface charge densities $ + \sigma $ and $ - \sigma $ respectively, are separated by a small distance. The medium between the plates is vacuum. If ${\varepsilon _0}$ is the dielectric permittivity of vacuum, then the electric field in the region between the plates is
- A$0\,volts/meter$
- B$\frac{\sigma }{{2{\varepsilon _o}}} volts/meter$
- ✓$\frac{\sigma }{{{\varepsilon _o}}} volts/meter$
- D$\frac{{2\sigma }}{{{\varepsilon _o}}} volts/meter$
