I've been zapped by the Van de Graaff generator more than a few times this past couple of weeks. It gets the adrenaline going, but it's definitely not pleasant! Our VDG can get up to 300,000 V! I don't think I've been shocked at that level, but even if I did, it would be far from lethal. And here's the thing: you're taught from childhood that playing with a power outlet at a 110 V can be lethal. How might you account for this difference in outcome? You might begin by calculating the amount of charge on the dome, using the eXpression you found in problem 2 while assuming a dome diameter of 10 cm
