A Parallel-Plate Air-Filled Capacitor Is Made from Two Plates That $0.062 \mathrm {~J} / \mathrm { m } ^ { 3 }$

question 147

Short Answer

A parallel-plate air-filled capacitor is made from two plates that are 0.070 m on each side and spaced 9.2 mm apart.What must the potential difference between the plates be to produce an energy density of $0.062 \mathrm {~J} / \mathrm { m } ^ { 3 }$ in the region between them? (ε₀ = 8.85 × 10^-12 C²/N ∙ m²)
