The force F (in N) acting between a particle with a charge q and a round disk with a radius R and a charge Q is given by the equation: c2/(Nm2) is the permittiv- where ,-0.885 10-12 ity constant and z is the distance to the particle. Con- sider the case where Q=9.4 10-6 C, q = 2.4 10-5 C, and R = 0.1 m. Make a plot of F as a function of z for 0sz s 0.3 m. Use MATLAB's built-in function max to find the maximum value of F and the corresponding distance z
