A pendulum consists of a small object of mass 2.9 kilogram hanging at the end of a 2.0 meter long light string that is connected to a pivot point.
(a) Evaluate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes an 8 degree angle with the vertical.
N•m
(b) Does the torque increase or decrease as the angle increase?
increase
decrease
