A constant force $F$ is applied in horizontal direction as shown in figure. Contact force between $M$ and $m$ is $N$ and between $m$ and $M'$ is $N'$ then
$N$ and $N'$ are equal
$N > N'$
$N' > N$
cannot be determined
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
For the given figure what will be the contact force applied by $6\ kg$ block on $4\ kg$ block ............ $N$
On a smooth plane surface (figure) two block $A$ and $B$ are accelerated up by applying a force $15\, N$ on $A$. If mass of $B$ is twice that of $A$, the force on $B$ is ........... $N$
$T_1$ and $T_2$ in the given figure are
In the following figure, the object of mass $m$ is held at rest by a horizontal force as shown. The force exerted by the string on the block is
