The chargeQc isunknown. What do we know about the signs of these charges if:In the y-direction, there is no net force on apositive charge situated at the origin.In the x-direction, a net force is experienced by a positivecharge situated at the

Four particles, a, b, c and d are situated, respectively, at (+1.0 m, 0), (0, +1.0 m), (-1.0 m, 0), (0, -1.0 m). It is known that the charges of three of the particles are qa, qb and qd and that these charges are equal in magnitude, but their signs are unknown. The charge Qc is unknown. What do we know about the signs of these charges if: In the y-direction, there is no net force on a positive charge situated at the origin. In the x-direction, a net force is experienced by a positive charge situated at the origin. This force acts in the positive x-direction. Which of the following is true? Charges qb and qd have the same sign: both are positive or both are negative. The magnitude of the charge of Qc is greater than that of qa. All charges are positive. If qb is positive, qd is also positive. If Qc < qa then the sign of Qc is negative. If qb is negative, qd is also negative. If Qc and qa are both negative, |qb| < |Qc|. If qb is positive, qd is negative. If |Qc|=|qa| then Qc is positive and qa is negative. If qb is positive, qd is also positive. If |Qc|=|qa| then Qc is positive and qa is negative.
