A wheel is subjected to uniform angular acceleration about its axis. Initially its angular velocity is zero. In the first 2 seconds, it rotates through an angle \( \theta_{1} \). In the next 2 seconds, it rotates through an
\( \mathrm{P} \) additional angle \( \theta_{2} \). Find the ratio of \( \theta_{2} / \theta_{1} \).
