Document Summary
In the lab instructions, it stated that there may be a standard deviation of 0. 5 v for the reading of the voltmeter. =(cid:882). (cid:890)(cid:889)(cid:882) (cid:2869)=(cid:2869)((cid:2869))=. (cid:888)(cid:883)(cid:887) (. (cid:887)(cid:883)(cid:885))= . (cid:882)(cid:884)(cid:886) (cid:2870)=(cid:2870)((cid:2869))=. (cid:890)(cid:883)(cid:890) (. (cid:887)(cid:884)(cid:884))= . (cid:882)(cid:883)(cid:891) (cid:2871)=(cid:2871)((cid:2869))=. (cid:891)(cid:889)(cid:882) (. (cid:887)(cid:885)(cid:882))= . (cid:882)(cid:883)(cid:888) (cid:2872)=(cid:2872)((cid:2869))=.

From the experiment we have discovered that the sum is in fact o volts for all 4 trails. Number of charge tranfsers y = 0. 032x + 1. 0733. Number of charge transfers s t l o v e g a t l o. 3 s t l o v e g a t l o. Data from section v1-1: net charge on sphere a = 0. Data from section v1-2: net charge on sphere a < 0.
