A container contains a liquid of density $\rho .$  It is accelerated so as to have a horizontal component of acceleration equal to $g$  and a vertically upward component also equal to  $g$ 

Match the enteries in Column I with respect to entries in Column II.
 

Column-I		Column-II
a)	Liquid surface makes an angle $\alpha$  with horizontal. $\tan \alpha =$	P)	4
b)	A wooden block is held under water with the help of a string tied to the base. The string makes an angle $\beta$  with horizontal. $\tan \beta =$	Q)	2
c)	A point A on the left wall is at a height 2cm above the base. B is another point on the base at a distance $x$  from the left wall. Pressure at A and B are equal. Value of  $x$ in cm is	R)	$\frac{1}{2}$
d)	Angle between the line AB and free surface of the liquid is $\varphi .$ $\tan \varphi =$	S)	0
