Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion (A): A cloth covers a table. Some dishes are kept on it The cloth can be pulled out without dislodging the dishes from the table. 

Reason (R): For every action there is an equal and opposite reaction.

In the light of the above statements, choose the correct answer from the options given below

A gun applies a force F on a bullet which is given by $F = (100 - 0.5 10^5 \times t )N$. The bullet emerges out with speed $400 \,m/s^{-1}$. Then find out the impulse exerted till force on bullet becomes zero
A cart has mass 2 metric ton and sand of 1 metric ton is inside the cart. Now a force of 10 N is applied on cart and sand starts to leak with rate of 0.5 kg/s. What is the velocity of cart when total sand has come out from the cart ?
In the diagram $100 \,kg$ block is hanging from a pulley and force $F$ is applied on the string to keep the system in equilibrium. If the whole system is moving up with a constant velocity $v$, then tension at point $P$ in the string will be
A rocket works on the principle of conservation of linear momentum. Higher the velocity, smaller is the pressure and vice-versa.
A boy stands on a weighing machine inside a lift. When the lift is going down with acceleration $g/4$, the machine shows a reading $30 \,kgf$. When the lift goes upwards with acceleration $g/4$, the reading would be
The figure shows a horizontal force $ \vec{F}$ acting on a block of mass M on an inclined plane (angle $\theta$). What is the normal reaction $N$ on the block?
Pseudo force is an imaginary force which is recognised only by a non-inertial observer to explain the physical situation according to Newton?? laws. Pseudo force has no physical origin, i.e., it is not caused by one of the basic interactions in nature. It does not exist in the action-reaction pair.
Consider the system shown in figure. The pulley and the string are light and all the surfaces are frictionless. The tension in the string is (take g = 10 m s)
A gun of mass 10 kg fires 4 bullets per second. The mass of each bullet is 20 g and the velocity of the bullet when it leaves the gun is 300 ms. The force required to hold the gun when firing is
The angular amplitude of a simple pendulum is $ \theta_{0} $ The maximum-tension in its string will be
Use of ball bearings between two moving parts of a machine is a common practice. Ball bearings reduce vibrations and provide good stability
A block of mass 2 kg is placed on the floor. The coefficient of static friction is 0.4. If a force of 2.8 N is applied on the block parallel to the floor, the force of friction between the block and the floor is (g = 10 m s)
A 0.2 kg object at rest is subjected to a force $\left(0.3\hat{i}-0.4\hat{ j}\right)$ N. What is the velocity after 6 s?
The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of a body. The part of the weight is spent in producing downward acceleration, when body is in elevator.
Impulsive force is large and acts for a short time. Finite change in momentum should be produced by the force.
In the figure given the position-time graph of a particle of mass $0.1\, kg$ is shown. The impulse at $t=2\, s$ is :
The driver in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference. A reference frame in which Newton?? laws of motion are applicable is non-inertial.
A particle is revolving in a circle of radius $R$. If the force acting on it is inversely proportional to $R$, then the time period is proportional to
A body is allowed to slide down a frictionless track freely under gravity. The track ends in a semicircular shaped part of diameter D. What should be the minimum height from which the body must fall so that it completes the circle.
If a cyclist moving with a speed of $4.9\, m / s$ on a level road can take a sharp circular turn of radius $4 \,m$, then coefficient of friction between the cycle tyres and road is
On a rainy day, it is difficult to drive a car or bus at high speed. The value of coefficient of friction is lowered due to wetting of the surface.
Conservation of linear momentum is equivalent to
If the radii of circular paths of two particles of same masses are in the ratio $1 : 2$, then to have a constant centripetal force, their velocities should be in a ratio of
The motion of a rocket is based on the principle of conservation of
