To find p, we use

to find the value p. As a sample calculation…

With this formula, we can tabulate p for different set of V1 and V2

To find sum of the electrometer(Vsum), we add both V blue and Vwhite. As a sample calculation…

Vsum = V blue + Vwhite

Vsum = -20 + 20

Vsum = 0

Based on calculation, we can make a complete table that shows calculated sum of the

electrometer and experimental sum of the electrometer.

This shows that estimated value and actual calculation are about the

same. There may be a small difference due to loss of electrons while

inserting charge producers into the pail.
