Using MATLAB

4. From physics, the capacitance (in F) between 2 parallel plates, filled with a dielectric material of relative permittivity E, can be approximated by the equation: C A/d, where A is the area of the plates (in sq.m), d is the distance (in m) between the plates, and Eo is the electric constant, 8.854x10-12 F/m a. Write a function M-file to find the capacitance between two rectangular parallel plates, with inputs: the length and width of the plates (both in m), the permittivity of the dielectric material separating the plates, and the distance between the plates (in m); and with output: the capacitance between the two plates (in F). b. After debugging your code, use your program to find: the capacitance between parallel rectangular plates of length 3 mm and width 4 mm, separated by distance d 0.2 mm, if the relative permittivity of the material between the plates is 2.5. (Be careful with the units.)
