Let $\mathrm{i}_{\mathrm{E}}$, $\mathrm{i}_{\mathrm{C}}$ and $\mathrm{i}_{\mathrm{B}}$ represent the emitter current, the collector current and the base current respectively in a transistor. Then,
Column $I$ shows four situations of standard Young's double slit arrangement with the screen placed far away from the slits $S_1$ and $S_2$. In each of these cases $\mathrm{S}_1 \mathrm{P}_0=\mathrm{S}_2 \mathrm{P}_0, \mathrm{~S}_1 \mathrm{P}_1-\mathrm{S}_2 \mathrm{P}_1=\lambda / 4$ and $\mathrm{S}_1 \mathrm{P}_2-\mathrm{S}_2 \mathrm{P}_2=\lambda / 3$, where $\lambda$ is the wavelength of the light used. In the cases $\mathrm{B}, \mathrm{C}$ and $\mathrm{D}$, a transparent sheet of refractive index $\mu$ and thickness $t$ is pasted on slit $\mathrm{S}_2$. The thicknesses of the sheets are different in different cases. The phase difference between the light waves reaching a point $\mathrm{P}$ on the screen from the two slits is denoted by $\delta(\mathrm{P})$ and the intensity by $I(\mathrm{P})$. Match each situation given in Column $I$ with the statement$(s)$ in Column $II$ valid for that situation.

$(B)$ $(\mu-1) t=\lambda / 4$ $Image$ $(q)$ $\delta\left(\mathrm{P}_1\right)=0$

$(C)$ $(\mu-1) t=\lambda / 2$ $Image$

$(r)$ $I\left(\mathrm{P}_1\right)=0$
$(D)$ $(\mu-1) t=3 \lambda / 4$ $Image$ $(s)$ $\left(\mathrm{P}_0\right)>I\left(\mathrm{P}_1\right)$
  $(t)$ $I\left(\mathrm{P}_2\right)>I\left(\mathrm{P}_1\right)$

A convex lens forms a real image of an object for its two different positions on a screen. If height of the image in both the cases be 8 cm and 2 cm, then height of the object is
 
In an optics experiment, with the position of the object fixed, a student varies the position of a convex lens and for each position, the screen is adjusted to get a clear image of the object. A graph between the object distance $u$ and the image distance $v$, from the lens, is plotted using the same scale for the two axes. A straight line passing through the origin and making an angle of $45 ^o $ with the $x-$axis meets the experimental curve at $P$. The coordinates of $P$ will be
