1) An evacuated tube uses an accelerating voltage of 44 kV toaccelerate electrons to hit a copper plate and produce X-rays.Ignoring relativistic effects, what would be the maximum speed ofthese electrons?
2) A battery-operated car uses a 12.0-V system. Find the chargethe batteries must be able to move in order to accelerate the 600kg car from rest to 30.0 m/s.
3) I want to accelerate an electron to the speed of sound (343m/s) by electrostatic force alone. To do so I’ve devised a way tostore as much charge as I’d like at a single fixed point which willbe located 0.35 m from the electron. How much charge do I need toaccumulate to accomplish my goal?
