To find the electric potential at the center of a non-conducting semi-circular rod with a uniformly distributed charge of \(-Q\), we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Setup**: We have a semi-circular rod with a radius \( R \) and a total charge of \(-Q\) uniformly distributed along its length. The center of the semi-circle is the point where we want to calculate the electric potential. 2. **Charge Element**: ...
