Question
Pivot point The figure shows an overhead view of a meter stick that can pivot about the point indicated, which is to the left of the stick's midpoint. Two horizontal forces, F and F2, are applied to the stick. Only F is shown. Force F2 is perpendicular to the rod and applied at the right end. If the torque on the rod is zero, a. F2 points upward and has a larger magnitude than F b. F2 points upward and has a smaller magnitude than F c. F2 points downward and has a larger magnitude than F d. F2 points downward and has a smaller magnitude than F e. F2 points upward and has the same magnitude as that of FExplanation / Answer
option d is correct.
Torque = 0, so F1*r1 - F2*r2 = 0 , so direction of F2 is same as F1 ie downward.
r2 > r1, so F2< F1.
