According to the law of conservation of momentum,a)the momentum of an ...
The law of conservation of momentum states that the total momentum of an isolated system of interacting particles is conserved. Let's break down this concept and understand why option 'C' is the correct answer.

What is momentum?
Momentum is a fundamental concept in physics that describes the motion of an object. It is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be calculated as p = m * v, where m is the mass of the object and v is its velocity.

Conservation of momentum
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that when two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction. As a result, the total momentum of the system remains constant.

Isolated system
An isolated system refers to a system in which no external forces are acting on it. In other words, there are no external influences that can change the momentum of the system. This could be a closed box or a system in which the external forces are negligible.

Interacting particles
Interacting particles are objects that exert forces on each other. When these particles collide or interact in any way, they exchange momentum. The law of conservation of momentum states that the total momentum of the system remains constant before and after the interaction, as long as no external forces are involved.

Option 'C'
Now, let's relate these concepts to the given options. Option 'C' states that the total momentum of an isolated system of interacting particles is conserved. This is correct because an isolated system ensures that there are no external forces, and interacting particles exchange momentum without any external influence. Hence, the total momentum of the system remains constant.

Options 'A' and 'B' are incorrect because they do not mention the requirement of an isolated system. In option 'A', the conservation of momentum is limited to an isolated system, not any system. Option 'B' introduces the concept of fields, which are not necessary for the conservation of momentum in an isolated system of particles.

Option 'D' is incorrect because it states that the momentum of an interacting system of particles and fields is conserved, which is not always true. The conservation of momentum depends on the presence of external forces and the isolation of the system, rather than the involvement of fields.

In conclusion, the correct answer is option 'C' because the law of conservation of momentum specifically applies to an isolated system of interacting particles.

Similar Class 11 Doubts

Newton's CradleThe device consists of a row of five metal balls positioned to just barely touch one another suspended from a frame by thin wires. On a small cradles, the balls are hung from the crossbars by light wire, with the balls at the point of an inverted triangle. This ensures that the balls can only swing in one plane, parallel to the crossbars. If the ball could move on any other plane, it would impart less energy to the other balls in the impact or miss them altogether, and the device wouldn't work as well, if at all. All the balls are, ideally, exactly the same size, weight, mass and density. As long as the balls are all the same size and density, they can be as big or as small as you like. The balls must be perfectly aligned at the center to make the cradle work the best.When a ball on one end of the cradle is pulled away from the others and then released, it strikes the next ball in the cradle, which remains motionless. But the last ball on the opposite end of the row is thrown into the air, then swings back to strike the other balls, starting the chain reaction again in reverse. This device illustrates the three main principles of Physics - conservation of energy, conservation of momentum and friction. Everything that moves has momentum equal to its mass multiplied by its velocity. Like energy, momentum is also conserved. Momentum is a vector quantity, when 1st ball hits 2nd ball, it's traveling in a specific direction, let's say east to west. This means that its momentum is also moving east to west. Any change in direction of the motion brings a change in the momentum, which cannot happen without the influence of an outside force. That is why 1st ball doesn't simply bounce off 2nd ball, the momentum carries the energy through all the balls in a westward direction. It is to remember that the law of conservation only works in a closed system, which is free from any external force. The Newton's cradle is not a closed system. When 5th ball swings out away from the rest of the balls, it is affected by the force of gravity, which brings the ball down. But, the horizontal line of balls at rest, functions as a closed system, free from any influence of any force other than gravity. It's here, during the small time between the first ball's impact and the 5th ball swinging out, that momentum is conserved.When the momentum is conserved in Newton’s cradle?
