The capacitance of two parallel conductors of length L and radius r, separated by a distance d in air, is given by

where ∊ is the permittitivity of air (∊ = 8.854 × 10−12 F/m). Create a cell array of capacitance values versus d, L, and r for d = 0.003, 0.004, 0.005, and 0.01 m; L = 1, 2, 3 m; and r = 0.001, 0.002, 0.003 m. Use MATLAB to determine the capacitance value for d = 0.005, L = 2, and r = 0.001.
