I wasn't for sure where to start with this problem. It is the first of 3 so if I understand how to do this one, I will be able to most likely get the others. I'm pretty sure that I need to make a free-body diagram of the forces in this situation but wasn't for sure where to label the friction force.(adsbygoogle = window.adsbygoogle || []).push({});

A 11 kg sphere is help against a wall by a string being pulled at an angle of 62 degrees. Given: f is the magnitude of the frictional force, and W=Mg.

If the net torque is equal to zero for the center of the sphere, that leads to which of the following?

1.Fsin(angle)=f

2.F+W=f

3.Fcos^2(angle)=f

4. F=f

5.W=f
