7. Analysis of an electrical circuit made up of a power source, resistor, capacitor, and inductor, leads to the following equation for capacitor charge as a function of time. q=q0e2LRtcos[tLC1(2LR)2] Write a program in VBA for Excel which calculates the charge at a specified time, t, and with specified circuit properties (resistance, R, inductance, L, capacitance, C, and initial charge, q0). The program should prompt the user for these values via input boxes, and should display the output in a message box. A run button should be placed on the first sheet. Include detailed comments on your code, explaining the features. Use the following data when testing your code t=0.1s,q0=12.4C,R=40,L=5H,C=104F
