Exercise 28

A 1-megabit computer memory chip contains many 60.0 × 10 15 -F capacitors. Each capacitor has a plate area of 21.0 × 10 12 m 2. Determine the plate separation of such a capacitor. (Assume a parallel-plate configuration.) The diameter of an atom is on the order of 10 10 m 5 1 Å. Express the plate separation in angstroms.
