Ozone layer exists at oan altitude of

Options

A. ionosphere
B. mesosphere
C. troposphere
D. stratosphere

Answer

D

Explanation

Suppose the charge on the capacitor at time `t` is Q. The electric field between the plates of the capacitor is `E=(Q)/(epsilon_(o)A)`. The flux through the area considered as
`Phi_(E)=(Q)/(epsilon_(0)A).(A)/(2)=(Q)/(2epsilon_(0))`.
The displacement current is
`i_(d)=(dPhi_(E))/(dt)=epsilon_(0)((1)/(2epsilon_(0)))(dQ)/(dt)=(i)/(2)`.
