Question

6.
In a parallel plate capacitor, the distance between
the plates is d and potential difference across
the plates is V. Energy stored per unit volume
between the plates of capacitor is [2001]




actually,answer is 1/2E0v^2/d^2. how to do this....​

Answer 1

Use formula ,

Energy stored per unit volume in a parallel plate capacitor , UE = 1/2 ( ε₀ × E²)

And we know that , E = V/d

so,

UE = 1/2 ( ε₀ × V²/d²)
