Two masses $m_{1}$ and $m_{2}$ are connected by a string over a frictionless pulley of negligible mass. The masses are released from rest. Air resistance is negligible.

Mass $m_{2}$ accelerates downwards at $\frac{g}{2}$ . What is $\frac{m_{1}}{m_{2}}$ ?
A. $\frac{1}{3}$

B. $\frac{1}{2}$

C. 2

Examiners report

With a low difficulty index for both, this question was challenging for both HL and SL candidates. Option B was the most common (incorrect) answer, and only a small number of candidates correctly selected option A. This question would be a useful teaching tool for students, as they consider the relationship between variables without numeric substitution.
