Consider a body of mass $3\,kg$ at rest on a smooth horizontal table. This body is  connected by a light string, which passes over a smooth pulley at the edge of the  table, to another body of mass $2\, kg$ hanging freely. This $2\, kg$ mass is released  from rest. Now consider the following statements :-

$(A)$ The masses remains at rest

$(B)$ The $3\,kg$ mass moves uniformly while $2\, kg$ mass moves with acceleration $\frac{2}{5}\, g \,m/s^2$

$(C)$ Both bodies move with acceleration $\frac{2}{5} \,g \,m/s^2$

$(D)$ The tension in the string near the first body is more than that near the second  body 

$(E)$ The tension in the string is $\frac{6g}{5}\, N $

Then the correct statements are

Shown in the diagram is a system of two bodies, a block of mass $m$ and a disc of mass $4\ m$ , held in equilibrium. If the string $3$ is burnt, find the acceleration of the disc. Neglect the masses of the pulleys $P$ and $Q$ . The co-efficient of friction between the block and horizontal surface is $0.5$ and friction between disc and string is zero ........ $m/s^2$
A rocket has an initial mass of $20 \times {10^3}\,kg$. If it is to blast off with an initial acceleration of $4\,m{s^{ - 2}}$, the initial thrust needed is  $(g = 10\,m{s^{ - 2}})$
Two masses $M$ and $M/2$ are joint together by means of a light inextensible string passes over a frictionless pulley as shown in figure. When bigger mass is released the small one will ascend with an acceleration of

A particle is moved from $(0, 0)$  to $(a, a)$  under a force $F = (3\hat i + 4\hat j)$ from two paths. Path $1$ is $OP$ and path $2$  is $OQP$ . Let $W_1$ and $W_2$ be the work done by this force in these two paths respectively. Then
A bullet of mass $0.01\, kg$ and travelling at a speed of $500\, m/s$ strikes and passes horizontally through a block of mass $2\,kg$ which is suspended by string of string of length $5\,m$. The centre of gravity of the block is found to raise a vertical distance of $0.1\,m$. What is the speed of the bullet after it emerges from the block .......... $\mathrm{m}/ \mathrm{s}$ $[g = 9.8\,m/s^2]$ (time of passing of bullet is negligible)
Body $A$ of mass $4 \;\mathrm{m}$ moung with speed $u$ collides with another body $B$ of mass $2\; \mathrm{m}$, at rest. The collision is head on and elastic in nature. After the collision the fraction of energy lost by the colliding body $A$ is
