(10%) problem 8: two particles which have the same magnitude charge but opposite sign are held r = 6 nm apart. particle i is then released while particle ii is held steady; the released particle has a mass of 9.91 × 10-23 kg. particle i's speed is 110 km/s when it is 0.76r away from particle ii.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
