Figure shows electrons 1 and 2 on an x axis and charged ions 3 and 4 of identical charge ?? q and at identical angles ?. Electron 2 is free to move; the other three particles are fixed in place at horizontal distances R from electron 2 and are intended to hold electron2 rn place. For physically possible values of q (a) Smallest,(b) Second smallest, and(c) Third smallest values of ? f or which electron 2 is held in place?
