281952 It is desired to photograph the image of an object placed at a distance of $3 \mathrm{~m}$ from the plane mirror. The camera which is at a distance of $4.5 \mathrm{~m}$ from the mirror should be focused for a distance of

1 $3 \mathrm{~m}$
2 $4.5 \mathrm{~m}$
3 $6 \mathrm{~m}$
4 $7.5 \mathrm{~m}$

281953 Two plane mirrors are inclined to each other at angle $60^{\circ}$. Ray incident on first mirror parallel to the second mirror becomes parallel to first mirror after reflection. Angle of deviation is

1 $30^{\circ}$
2 $60^{\circ}$
3 $90^{\circ}$
4 $120^{\circ}$

281954 A concave mirror is placed on a horizontal table with its axis directed vertically upward. Let $O$ be the pole of the mirror and $\dot{C}$ its centre of curvature. A point object is placed at $\mathrm{C}$. It has real image, also located at $\mathrm{C}$. If the mirror is now filled with water, the image will be

1 Real and remain at $\mathrm{C}$
2 Real and located at a point between $\mathrm{C}$ and $\infty$
3 Real and located at a point between $\mathrm{C}$ and $\mathrm{O}$
4 None of these
