Create an Excel graph of Electrometer voltage vs$.$ d$.$ How does $V$ vary with d$?$

Create another Excel graph of $\frac{1}{V}$ vs$.1/$d$.$ Describe this relationship. Add a trend line and trend line equation including correlation coefficient. Also do LINEST and note the uncertainty in slope and $y-$intercept.

What does the slope represent? Show how the slope gives the constant charge, Q$,$ on the plates. $[$Hint: See Eq$.2.]$

What does the $y-$intercept represent? Calculate the System Capacitance from this. $[$Hint: See Eq$.2.]$

The diameter of the circular plate is $0\mathrm{.}02$m and the area is $3\mathrm{.}142$e$-4$ m$^2.$ Please do $10,11,12$ and $13.$ Thank you
