Question

Plates of a parallel plate capacitor, having a potential difference 100 V applied across them, carry a surface charge density of 50 nC c m - 2 . Spacing between the plates is, 329 μ m, 259 μ m, 177 μ m, 125 μ m

MARKS App · Accepted Answer

E = σ ε 0 Potential difference V = E d ∴ d = V E = 100 50 × 10 - 7 × 8.85 × 10 - 12 = 177 × 10 - 6 m = 177 μm
