A thin rectangular magnet suspended freely has a period of oscillation equal to $T$. Now, it is broken into two equal halves (each having half of the original length) and one piece is made to oscillate freely in the same field. 1f its period of oscillation is $T'$, the ratio $T'/T$ is

The charge on a particle Y is double the charge on particle X. These two particles X and Y after being accelerated through the same potential difference enter a region of uniform magnetic field and describe circular paths of radii R1 and R2 respectively. The ratio of the mass of X to that of Y is
