2. Capacitance and distance C=A/d In this part the area, A, of the plate is kept constant A= 100x10^-6 m^2 and the distance d between the plates is changed. You

are to record the values for distance(in m) and the capacitance C (in F). Take at least eight values of d and C, and then fill the table below by calculating (1/d). Remember to write in your units of measure in the table. 1- Use Excel to plot the relationship between (1/d) and C. Sketch the graph or insert a screenshot. Comment on the graph's appearance. 2- Draw the best straight-line equation and determine its slope. 3- From the slope, determine the value of the permittivity of free space . 4- Determine the percentage error using the real value = 8.85X10^-32 C^2/N.m^2
