In this week's lecture #3, Walter Lewin lit a fluorescent bulbby holding it near a Van de Graaff generator, charged to 300,000 V.Suppose that the spherical conductor of the Van de Graaff has adiameter of 68.69 cm, that the bulb is 100.56 cm in length, andProf. Lewin is holding the near end of the bulb 32.23 cm from thesurface of the Van der Graaff. What is the potential difference (V)between the two ends of the bulb?
