A block is stationary on a rough inclined plane. How many forces are acting on the block?

In the given arrangement, the normal force applied by block on the ground is

Three blocks are placed as shown in figure. Mass of $A, B$ and $C$ are $m_1, m_2$ and $m_3$ respectively. The force exerted by block$\text{'}C\text{'}$ on $\text{'}B\text{'}$ is

The value of $\frac{T_3}{T_1}$ is

A block of mass $10 \mathrm{kg}$ is moving on a rough surface as shown in figure. The frictional force acting on block is

Block of mass $10 \mathrm{kg}$ is moving on inclined plane with constant velocity $10 \mathrm{m} {\mathrm{s}}^{-1}.$ The coefficient of kinetic friction between incline plane and block is

The ratio of acceleration of blocks $A$ placed on smooth incline with block $B$ placed on rough incline is $2: 1.$ The coefficient of kinetic friction between block $B$ and incline is

A block of mass $10 \mathrm{kg}$ is released on rough incline plane. Block start descending with acceleration $2 \mathrm{m} {\mathrm{s}}^{-2}.$ Kinetic friction force acting on block is $\left(\mathrm{take} \mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$
