Question

A point charge Q_(1) = 20 μC is at (-d,0) while Q_(2) = -10 μC is at (+d,0). Take d = 1.0 m and x = y = 2 m. (a) Find the resultant field at a point with coordinates (x, y). (b) Besides infinity, at what point would the net field be zero? (c) What's the electric force on Q_(3) = -2 μC? (Ans: {(3.5 × 10^3 (hat(ı)) - 8.6 × 10^3 (hat(ȷ))) (N/C); x = 5.8 m; (-7 × 10^(-3) (hat(ı)) + 17.2 × 10^(-3) (hat(ȷ))) N)}

Step 1

99 x 10^9 N m^2/C^2). For Q1 at (-d,0) = (-1,0) m and point (2,2) m, the distance r = sqrt((2+1)^2 + (2-0)^2) = sqrt(10) m. Therefore, the electric field due to Q1 at point (2,2) is E1 = k * Q1 / r^2 = (8.99 x 10^9) * (20 x 10^-6) / 10 = 1.798 x 10^3 N/C. Show more…
