Chapter 23, Problem 5Q

In Fig. 23-25, an election is released between two infinite nonconducting sheets that are horizontal and have uniform surface charge densities σ_(+); and σ_(−), as indicated. The electron is subjected to the following three situations involving surface charge densities and sheet separations. Rank the magnitudes of the election’s acceleration, greatest first.

Situation	σ(+)	σ(−)	Separation
1	+4σ	−4σ	d
2	+7σ	−σ	4d
3	+3σ	−5σ	9d
