plz answer this question !!!!
Derive an expression for the energy stored in a parallel plate capacitor with air as the medium
between its plates. How does the total energy stored by the capacitor change when the medium of air
is replaced by a medium of dielectric constant k ? Explain.

Answer:
Derive an expression for energy stored in a parallel plate capacitor fo capacitane C with air as medium between the plates having charges Qand-Q. Show that this energy can be expressed in terms of electric field as 12∈0E2 Ad, where A is area of each plate and d is the separation between the plates.
Electrostatic Potential and Capacitance. (v) energy stored in the capacitor, change. ... Since, neither the potential difference nor the separation between the plates is changing therefore, the electric field remains unchanged. (iii) When, dielectric medium is introduced, capacity would increase by a factor of K.
Therefore, when air is replaced by dielectric medium, electrostatic force decreases by factor k.
