Suppose, we initiated a low velocity wave in a long rope tied to one end. After a short time we will initiate another high velocity wave in that same rope... U will find that after imposition its velocity will be greater than second one..... Hence i think it is applied for velocity... And if its true for velocity it must be true for kinetic energy...

Explanation:
The principle of superposition states that the net displacement of a particle on a string is the sum of the displacements produced by the two waves individually. This principle is valid because displacement is a vector quantity and can be added or subtracted.
However, when it comes to the net velocity of the particle and the kinetic energy of the particle, the principle of superposition does not hold true. This is because both velocity and kinetic energy are scalar quantities and cannot be added or subtracted in the same way as vectors.
Net Velocity:
Velocity is defined as the rate of change of displacement with respect to time. Since displacement can be added or subtracted, the net velocity can be calculated by adding or subtracting the individual velocities produced by the two waves. However, this would only give the net velocity at a particular point on the string at a specific time. It does not hold true for the entire string as a whole. Therefore, the principle of superposition is not valid for the net velocity of the particle.
Kinetic Energy:
Kinetic energy is defined as the energy possessed by an object due to its motion. It is directly proportional to the square of the velocity. Since velocity cannot be added or subtracted, the principle of superposition does not hold true for the kinetic energy of the particle.
Therefore, the correct answer is option 'B' - the principle of superposition is valid for the net displacement of a particle on a string, but not for the net velocity or the kinetic energy of the particle.
