Directions: Each of these questions contain two statements, Assertion...
Assertion: A bullet is fired from a rifle. If the rifle recoils freely, the kinetic energy of the rifle is more than that of the bullet.
Reason: In case of the rifle-bullet system, the law of conservation of momentum is violated.
To determine the correct answer, let's analyze the assertion and reason separately.
Assertion: A bullet is fired from a rifle. If the rifle recoils freely, the kinetic energy of the rifle is more than that of the bullet.
When a bullet is fired from a rifle, the two objects involved are the bullet and the rifle itself. The rifle recoils in the opposite direction to the bullet due to the conservation of momentum. According to the law of conservation of momentum, the total momentum of an isolated system remains constant if no external forces act on it. In this case, the momentum of the bullet and the rifle should be equal and opposite.
The kinetic energy of an object is given by the equation KE = (1/2)mv^2, where m is the mass of the object and v is its velocity. As the bullet is much smaller in mass compared to the rifle, we can assume that the velocity of the bullet is much greater than that of the rifle. Therefore, the kinetic energy of the bullet is expected to be greater than that of the rifle.
Reason: In the case of the rifle-bullet system, the law of conservation of momentum is violated.
The reason provided is incorrect. The law of conservation of momentum is not violated in the case of the rifle-bullet system. The momentum of the bullet and the rifle is conserved, even though their velocities are opposite in direction. The total momentum before the bullet is fired is zero, as the initial momentum of the bullet and the rifle in opposite directions cancel each other out. After the bullet is fired, the total momentum remains zero, as the momentum gained by the bullet is equal and opposite to the momentum gained by the rifle.
Therefore, the correct answer is option 'D' - Assertion is incorrect, reason is correct. The assertion is incorrect because the kinetic energy of the bullet is expected to be greater than that of the rifle, not the other way around. The reason is correct in stating that the law of conservation of momentum is not violated in the rifle-bullet system.

Directions: Each of these questions contain two statements, Assertion...
The Law of conservation of linear momentum is correct when no external force acts. When bullet is fired from a rifle then both should possess equal momentum but different kinetic energy. Kinetic energy of the rifle is less than that of bullet because E∝1/m. As the mass of the gun is larger, so the kinetic energy of the gun is less than that of bullet.
