Please write the matlab code for this problem correctly thank you

6.12 Capacitance of a Transmission Line The capacitance per meter of a single- phase two-wire transmission line is given by the equation D-r (6.15) In where C is the capacitance in farads per meter of line, ,-410-7 F/m is the permittivity of free space, D is the distance between the two conductors and r is the radius of each conductor. Write a function that calculates the total capacitance of a transmission line as a function of its length in kilometers the spacing between the two conductors, and the diameter of each conductor. Use this function to calculate the capacitance of a 100 km transmission line with conductors of radius r = 2 cm and distance D = 1.5 m. 6.13 What happens to the inductan
