Here is the answer for the question – **1. A rod of length L is pivoted about its left end and has a force F applied perpendicular to the other end. The force F is now removed and another force F’ is applied at the midpoint of the rod. If F’ is at an angle of 30o with respect to the rod, what is its magnitude if the resulting torque is the same as when F was applied?**. You’ll find the correct answer below

### 1. A rod of length L is pivoted about its left end and has a force F applied perpendicular to the other end. The force F is now removed and another force F’ is applied at the midpoint of the rod. If F’ is at an angle of 30o with respect to the rod, what is its magnitude if the resulting torque is the same as when F was applied?

**The Correct Answer is**

**4F**

### Reason Explained

4F is correct for 1. A rod of length L is pivoted about its left end and has a force F applied perpendicular to the other end. The force F is now removed and another force F’ is applied at the midpoint of the rod. If F’ is at an angle of 30o with respect to the rod, what is its magnitude if the resulting torque is the same as when F was applied?
