A cubical block having square cross-section of side 2 m and of mass M=10kg is resting over a platform moving at constant acceleration  $a=1m/s^2$. Coefficient of friction between the block and the platform is $\mu =0.1$ . A horizontal force F acts at the top of the cube as shown in figure. Now match column-I with column-II. ( Take $g=10m/s^2$ )

Column-I		Column-II
A)	F=0	P)	Block neither topples nor slips over the platform
B)	F=85 N	Q)	Block topples but does not slip over the platform
C)	F=15 N	R)	Block slips but does not topple over the platform
D)	F=25 N	S)	Block slips as well as topples on the platform
