The potential energy of charged parallel plate capacitor is v₀ . If a slab of dielectric constant K is inserted between the plates, then the new potential energy will be
Options
- Av₀ K
- Bv₀ K^2
- Cv₀ K^2
- Dv₀ ^2
Correct answer
A. v₀ K
Step-by-step solution
We know, v₀= Q^2 2 C On inserting the slab of dielectric constant k , the new capacitance C ^ = KC New potential energy v₀^ = Q ^2 2 C ^ v₀^1= Q^2 2 KC = v₀ ~K
