MHT CET 2026 Physics question
A parallel plate air capacitor having area of each plate 'A' and the distance between the plates 'd' has uniform electric field E in the space between the plates. The energy stored in the capacitor is ( = permittivity of free space.)
Answer: (C)
Solution
The energy density of an electric field in free space is . The field is uniform in the volume between the plates, . Energy stored . Check using with $C =
