Quizplus · Accepted Answer

Using Coulomb's law, we can calculate the electric force on q: F = k * (Q₁*q/a^2 + Q₂*q/b^2) where k is Coulomb's constant: k = 9 * 10^9 N*m^2/C^2 Plugging in the given values, we get: F = 9 * 10^9 * (60 * 32 / 3^2 + 80 * 32 / 4^2) F ≈ 1.3 N Therefore, the answer is B.

If a = 30 Mm,b = 4
