AP Physics Multiple Choice Practice ? Torque 1. A uniform meterstick of mass 0.20 kg is pivoted at the 40 cm mark. Where should one hang a mass of 0.50 kg to balance the stick? ?(A) 16 cm (B) 36 cm (C) 44 cm (D) 46 cm (E) 54 cm 2. A uniform meterstick is balanced at its midpoint with several forces applied as shown below. If the stick is in equilibrium, the magnitude of the force X in newtons (N) is?(A) 50 N (B) 100 N (C) 200 N (D) 300 N (E) impossible to determine without the weight of the stick 3. A door (seen from above in the figures below) has hinges on the left hand side. Which force produces the largest torque? The magnitudes of all forces are equal.
