A parallel plate capacitor of plate area A and plates separation distance d is charged by applying a potential `V_(0)` between the plates. The dielectric constant of the medium between the plates is K. What is the uniform electric field E between the plates of the capacitor ?A. `E^(2)Ad//epsilon_(0)`B. `(1)/(2)epsilon_(0)E^(2)Ad`C. `epsilon_(0)EAd`D. `(1)/(2)epsilon_(0)E^(2)`

Answer» Correct Answer - B
`"Total energy = energy density"xx"volume"`
`=((1)/(2)epsilon_(0)E^(2))(Ad)`
