Which one of the following relationships between T and P must be true? A) T > P B) T = P C) P + T = 125 [N] D) P = T + 25 [N] E) P = T + 100 [N]

Step 1

This means that the net force acting on the system is zero. Second, we know that the tension T in the wire is 100 N. This force is acting upward. Third, we know that the pull P is also acting upward. Since the net force is zero, the sum of the upward forces Show more…
