(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A) A simple pendulum consits of a 2.1 kg point mass hanging at the end of a 4.3long light string that is connected to a pivot point.

a. Calculate the magnitude of the torque (due to the force of gravity) around this pivot point when the string makes a 4.6 degree angle with the vertical.

B) Repeat this calculation for an angle of 15.6 degrees.

2. Relevant equations

torque = mglsin(theta)

3. The attempt at a solution

I think the above equation is the right equation to use in this problem but I'm not sure what to plug in for theta. Is it the angle that's given or do I have to add 90 degrees to the given angle because the string makes the angle with the vertical? I have the same question for Part B as well. Thank you in advance for any help/advice.
