Consider three media P, Q and R with refractive indices 1, 1.25, and 1.5 respectively. The medium Q having a thickness of 5 cm is placed between extended media P and R as shown in the figure. An object O is placed at the centre of medium Q. If viewed from medium P near the normal direction, the apparent depth of O is $h_1$. For similar observation from medium R, the apparent depth is $h_2$. The value of $|h_{1}-h_{2}|$, in cm, is: [Image Placeholder]

Two identical inductors are connected in two different configurations P and Q, where a time varying current $l(t)$ is flowing, as shown in the figure. The induced emf between points a and b for configuration P is $E_{P}$ and that for configuration Q is $E_{Q}$ The ratio $E_{P}/E_{Q}$ is: [Neglect the effect of mutual inductance.] [Image Placeholder]
