Two fixed particles, each of charge 5.9 ✕ 10−6 C, are 8 cm apart. What force (in N) do they exert on a third particle of charge −2.3 ✕ 10−6 C that is 5 cm from each of them? (Express your answer in vector form. Assume that the +x-axis is to the right and the +y-axis is up along the page. Further assume that the two particles sit along the x-axis and the third particle sits above the x-axis.) F = ? N
