Two infinitely long parallel conducting plates having surface charge densities `+ sigma` and `-sigma` respectively, are seperated by a small distance. The medium between the plates is vacuum. If `epsilon_(0)` is the dielectric permittivity of vacumm, then the electric field in the region between the plates is

Options

A. 0 volt/meter
B. `sigma//2epsi_(0)` volt/meter
C. `sigma//epsi_(0)` volt/meter
D. `2 sigma//epsi_(0)` volt/meter

Answer

C

Explanation

Electric field between the plates is
`=(sigma)/(2 epsi_(0))-((-sigma))/(2epsi_(0))`
`=(sigma)/(epsi_(0))` volt/meter.
