The momentum $\mathrm{P}$ of an object varies with time $\left(\mathrm{t}\right)$ as shown in figure. The corresponding force $\left(\mathrm{F}\right)$-time $\left(\mathrm{t}\right)$ graph is

A block of $10 \mathrm{kg}$ mass is placed on a rough inclined surface as shown in figure. The acceleration of the block will be

A block (mass $=M \mathrm{kg}$) is placed on a rough inclined plane. A force $F$ is applied parallel to the inclined (as shown in figure) such that it just starts moving upward. The value of $F$ is

Figure shows two block system, $4 \mathrm{kg}$ blōck rešts on a smooth horizontal surface, upper surface of $4 \mathrm{kg}$ is rough. A block of mass $2 \mathrm{kg}$ is placed on its upper surface. The acceleration of upper block with respect to earth when $4 \mathrm{kg}$ mass is pulled by a force of $30 \mathrm{N}$, is

A force $\overrightarrow{F}=\hat{i}+4\hat{j}$ acts on the block shown. The force of friction acting on the block is

Two blocks of mass $M$ and $m$ are kept on the trolley whose all surfaces are smooth select the correct statement

Coefficient of friction between $A$ and $B$ is $\mu$. The minimum force $F$ with which $A$ will be pushed such that $B$ will not slip down is

A block of mass $10 \mathrm{kg}$ is held at rest against a rough vertical wall $[\mu =0.5]$ under the action a force $F$ as shown in figure. The minimum value of $F$ required for it is $\left(g=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$
