Concept explainers
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 |

- Show that the units 1 v2/Q = 1 W, as implied by the equation P = V²/R. Starting with the equation P = V²/R, we can get an expression for a watt in terms of voltage and resistance. The units for voltage, V, are equivalent to [? v2 v2 A, are equivalent to J/C ✓ X . Therefore, 1 = 1 = 1 A V1 J/s Ω V-A X = 1 W. . The units for resistance, Q, are equivalent to ?
