Which of the following statements are true: (Give ALL correct answers, i.e., B, AC, BCD...) If q1 is positive, q2 is negative, and q3 and positive, then q1 MIGHT feel a net force to the left. If q1 = q2 = -q3, then q1 MUST feel a net force to the right. If q1 is negative and q2 = q3 then the x-component of the electric field at the mid-point between q2 and q3 MIGHT point left. If q1=q2=q3, then the net electric field at the center of the triangle MUST be zero. If q1 is positive, q2 is negative, and q3 is negative, then q1 MIGHT feel a net force straight up.
