A Capacitor Is Made by Taking Two Sheets of Aluminum

Multiple Choice

A capacitor is made by taking two sheets of aluminum foil,each 0.022 mm thick and placing between them a sheet of paper which comes from a ream of 580 sheets,the ream being 5.4 cm thick with sheets measuring 216 mm by 279 mm (the usual 8 1/2 by 11) .What is the capacitance of the capacitor made this way if the dielectric constant of the paper is 3.7? (ε₀ = 8.85 × 10−¹² C²/N × m²)
