Unformatted text preview: Net force on q3 is to the left and its magnitude is the sum of the magnitudes of the two forces F13 and F23. F13 = k q1 q3/0.4^2 F23 = k q2 q3 / 1.1^2 Net force on q3 = F13 + F23 = k q1 q3/0.4^2 + k q2 q3 / 1.1^2 where k = 8.85 x10 ^12 Nm^2/C^2 Net force on q3 = k (q1 q3/0.4^2 + q2 q3 / 1.1^2) Net force on q3 = 8.85 x10 12 (10x109 x 50x109 /0.4^2 + 40x109 x 50x109 / 1.1^2) Net force on q3 = 8.85 x10 12 (10x50 /0.4^2 + 40x50 / 1.1^2) x 1018 Net force on q3 = 4.2 x 1026 N...
