A wheel is subjected to uniform angular acceleration about its axis. Initially its angular velocity is zero. In the first 2 sec, it rotates through an angle \[{{\theta }_{1}}\]. In the next 2 sec, it rotates through an additional angle \[{{\theta }_{2}}\]. The ratio of \[\sqrt{3}mg\] is [AIIMS 1985]
