Có hai điện tích q1 = + 2.10-6 (C), q2 = - 2.10-6 (C), đặt tại hai điểm A, B trong chân không và cách nhau một khoảng 6 (cm). Một điện tích q3 = + 2.10-6 (C), đặt trên đường trung trực của AB, cách AB một khoảng sẽ là 4 (cm). Độ lớn của lực điện do hai điện tích q1 và q2 tác dụng lên điện tích q3 là bao nhiêu?
