A) divide each cereal price by the amount of ounces. Brand A is $0.13888 (rounds to $0.14). B is $0.14583 (rounds to $0.15) So, since cereal band A is less cost per ounce, its cheaper
B) This question cannot be answered, since there is no table.
F = kq2 / r2 q = ne F = k(ne)2 / r2 n = âš(r2F / ke2) = (r/e) âš(F/k) k = 9 x 109 Nm2/C2 e = 1.6 x 10-19 C n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
