A wooden wedge of mass $M$ and inclination angle $(\alpha)$ rest on a smooth floor. A block of mass $m$ is kept on wedge. A force $F$ is applied on the wedge as shown in the figure such that block remains stationary with respect to wedge. So, magnitude of force $F$ is
$(M+m) g \tan \alpha$
$g \tan \alpha$
$m g \cos \alpha$
$(M+m) g \operatorname{cosec} \alpha$
Two wooden blocks are moving on a smooth horizontal surface such that the mass $m$ remains stationary with respect to block of mass $M$ as shown in the figure. The magnitude of force $P$ is
A block of mass $m$ slides on the wooden wedge, which in turn slides backward on the horizontal surface. The acceleration of the block with respect to the wedge is : Given ${m}=8 \,{kg}, {M}=16\, {kg}$
Assume all the surfaces shown in the figure to be frictionless.
Two blocks of mass $8\,kg$ and $2\,kg$ are connected by a string and they are released on a inclined plane of inclination $30^o$ as shown in figure then what will be the tension in string connecting the two blocks ............ $N$
A wedge of height $H$ (fixed) and inclination $\alpha $ (variable) is moving on a smooth horizontal surface with constant acceleration $g\ m/s^2$ . A small block is placed at bottom of incline as shown in figure, slips on the smooth surface of incline . Choose $CORRECT$ statement about time taken by block to reach the top of incline
Two blocks of $7\,\,kg$ and $5\,\,kg$ are connected by a heavy rope of mass $4\,\,kg.$ An upward force of $200\,N$ is applied as shown in the diagram. The tension at the top of heavy rope at point $P$ is ....... $N$ $(g = 10\,\,m/s^2)$
