Two horizontal rods are each held up by vertical strings tied to their ends. Rod 1 has length $L$ and mass $M$; rod 2 has length $2 L$ and mass $2 M$. Each rod then has one of its supporting strings cut, causing the rod to begin pivoting about the end that is still tied up. Which rod has a larger initial angular acceleration?

A. $\operatorname{Rod} 1$

B. $\operatorname{Rod} 2$

C. The initial angular acceleration is the same for both.
