AP Physics 1 Prep suspension point 60 m 8. In an effort to tighten a bolt, a force F is applied as 9. In the figure above, what is the torque about the pendu- shown in the figure above. If the distance from the end lum's suspension point produced by the weight of the of the wrench to the center of the bolt is 20 cm and bob, given that the length of the pendulum, L, is 80 cm F =20 N, what is the magnitude of the torque produced and m = 0.50 kg ? by F ? (A) 0.5 N.m (A) 1 N.m (B) 1.0 N.m (B) 2 N.m (C) 1.7 N.m (C) 4 N.m (D) 2.0 N.m (D) 10 N.m
