4 Q26.01 Consider the positive direction to be to the right. Then for each case: a) i = (– 7 C/s) = – 7 C/s b) i = – (3 C/s) + (– 4 C/s) = – 7 C/s c) i = – (2 C/s) + (– 5 C/s) = – 7 C/s d) i = – (6 C/s) – (– 1 C/s) = – 5 C/s Then, a = b = c > d Q26.06 a) E = V / L , so for (1) E = V / L , for (2) E = 2 V /2 L = V / L , for (3) E = 2

Unformatted text preview: V /3 L = (2/3) V / L. Therefore they must be ranked, (1) and (2) tied, and (3) lowest. b) J = E / ρ . Since is the same for all, they are ranked according to E . They must be ranked, (1) and (2) tied, and (3) lowest. c) v d = J /( ne ). Since ( ne ) is the same for all, they are ranked according to J . They must be ranked, (1) and (2) tied, and (3) lowest....
