An object O is kept on the principal axis of a concave mirror at a distance 200 cm from pole of the mirror. By some mechanism radius of curvature of mirror is changing with time as $\mathrm{R}=\frac{200}{\mathrm{t}}\mathrm{cm}$ here t is in second. Column–I shows the time instant Column–II represents velocity of image at that time and Column –III represents acceleration of image at the time

Time	Velocity of image	Acceleration of image
A) 1 sec	P) $\frac{400}{49}\mathrm{cm}/\mathrm{s}$	1)$-\frac{64}{5}\mathrm{cm}/{\mathrm{s}}^2$
B) 2 sec	Q) 16 cm/s	2) $-\frac{1600}{343}\mathrm{cm}/{\mathrm{s}}^2$
C) 3 sec	R)$\frac{400}{9}\mathrm{cm}/\mathrm{s}$	3)$-\frac{1600}{27}\mathrm{cm}/{\mathrm{s}}^2$
D)4 sec	S)400 cm/s	4) –1600 cm/s2
