1 Data Tables for ES1/ES2 PHY 158 Electrostatics The electrometer should always be on the 100 V scale. ES1 V-5 (Volts vs. Position) On the back, record what your expectation is before doing this exercise. Specifically, how do you anticipate voltage will vary as a function of position? # V 1/4 Volts 1/ 4 1/ 4 final V f V = V 1/2 Volts 1/ 2 1/ 2 final V f V = V 3/4 Volts 3/4 3/ 4 final V f V = V 1 Volts 1 1 final V f V = V final (Volts) 1 2 3 ES1 V-6 (Conservation of Charge) # V blue (Volts) V white (Volts) V final (Volts) 1 2 3 ES1 V-7 (Charging by Induction) # V insert (Volts) V ground (Volts) V withdr (Volts) V final (Volts) 1 2 3 ES1 V-4 (Fraction of charge deposited) Do 5 trials # V 1 (Volts) V 2 (Volts) 2 1 1 V p V = 1 2 3 4 5 Average:

Unformatted text preview: 2 ES1 V-8 (Voltage vs. deposited charge) Note: Use the 1000 V power supply. # V 5 (Volts) V 10 (Volts) V 15 (Volts) V 20 (Volts) V 25 (Volts) 1 2 Average: ES2 VA Use the 3000 V supply. Make certain that the polarity of the electrometer sensing cable and the electrometer output cable (to the DVM) have the correct polarity. θ = 90 °, d = 20 cm, Net charge on sphere A = 0 φ (deg.)
