Problem 7: Solve problem 21 on page 317 of Gilat's book: 1. Program a function that calculates the integrand. 2. Use the MATLAB quad function in order to calculate the integral numerically. 21. The electric field E due to a charged circular disk at a point at a distance z along the axis of the disk is given by -3/2 where is the charge density, is the permittivity constant, ,-8.85x 10-12 C2/N m), and R is the radius of the disk. Determine the electric field at a point located 5 cm from a disk with a radius of 6 cm, charged with = 300 C/m2. 1S
