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 ............ $N$
$40$
$10$
$30$
$0$
Figure shows four blocks that are being pulled along a smooth horizontal surface. The masses of the blocks and tension in one string are given. The pulling force $F$ is ............ $ N$
For frictionless surfaces in given arrangement tension $T_2$ is :-
A frictionless cart $A$ of mass $100\ kg$ carries other two frictionless carts $B$ and $C$ having masses $8\ kg$ and $4\ kg$ respectively connected by a string passing over a pulley as shown in the figure. What horizontal force $F$ must be applied on the cart so that smaller cart do not move relative to it .......... $N$
In the diagram shown, the normal reaction force between $2\,kg$ and $1\,kg$ is (Consider the surface, to be smooth)$.........N$ (Given $g =10\,ms ^{-2}$)
