The variety of question types ensured that candidates were evaluated on a wide range of skills, making it a comprehensive assessment of their physics knowledge.

Detailed Solutions and Analysis of Key Questions

Alright, let's roll up our sleeves and delve into some key questions from the NEET 2023 physics paper. We'll provide detailed solutions and analysis to help you understand the thought process and problem-solving strategies involved. Keep in mind that understanding the how and why behind each solution is more important than just memorizing the answer.

Question 1: Mechanics

Question: A body of mass m is moving with a velocity v. It collides elastically with another body of the same mass at rest. What is the velocity of the first body after the collision?

Solution: This question is based on the concept of elastic collision. In an elastic collision between two bodies of equal mass, where one body is initially at rest, the bodies exchange their velocities. Therefore, the velocity of the first body after the collision is 0.

Analysis: This was a relatively straightforward question that tested the understanding of basic concepts related to elastic collisions. Students who had a clear understanding of the principles of conservation of momentum and kinetic energy could easily solve this problem. Make sure you're crystal clear on the different types of collisions and their properties.

Question 2: Thermodynamics

Question: An ideal gas undergoes an isothermal process from state A to state B. The change in internal energy is:

Solution: In an isothermal process, the temperature remains constant. For an ideal gas, the internal energy depends only on the temperature. Therefore, if the temperature is constant, the change in internal energy is zero.

Analysis: This question tested the understanding of the properties of an isothermal process and the relationship between internal energy and temperature for an ideal gas. A clear understanding of the first law of thermodynamics would have been helpful in solving this problem. Remember, isothermal means constant temperature!

Question 3: Optics

Question: The refractive index of a medium is given by n = c/v, where c is the speed of light in vacuum and v is the speed of light in the medium. If the speed of light in a medium is 2 x 10^8 m/s, what is the refractive index of the medium?

Solution: We know that the speed of light in vacuum (c) is approximately 3 x 10^8 m/s. Given that the speed of light in the medium (v) is 2 x 10^8 m/s, we can calculate the refractive index (n) as follows:

n = c/v = (3 x 10^8 m/s) / (2 x 10^8 m/s) = 1.5

Analysis: This was a direct application of the formula for refractive index. Students who knew the formula and the speed of light in vacuum could easily solve this problem. Make sure you memorize the key formulas and constants! Understanding the relationship between refractive index and speed of light is crucial.

Question 4: Electromagnetism

Question: A charged particle is moving in a uniform magnetic field. The force on the particle is given by F = q(v x B), where q is the charge, v is the velocity, and B is the magnetic field. If the velocity and magnetic field are perpendicular to each other, what is the magnitude of the force?

Solution: When the velocity and magnetic field are perpendicular, the angle between them is 90 degrees. Therefore, the magnitude of the force is given by:

F = qvBsin(90°) = qvB

Analysis: This question tested the understanding of the Lorentz force law. Students who knew the formula and the conditions for maximum force (when v and B are perpendicular) could easily solve this problem. Don't forget the vector nature of the force and the importance of the angle between v and B.

Question 5: Modern Physics

Question: The de Broglie wavelength of a particle is given by λ = h/p, where h is Planck's constant and p is the momentum. If the momentum of a particle is doubled, what happens to its de Broglie wavelength?

Solution: If the momentum (p) is doubled, the de Broglie wavelength (λ) will be halved, since λ is inversely proportional to p.

Analysis: This question tested the understanding of the de Broglie wavelength and its relationship to momentum. A clear understanding of the wave-particle duality of matter would have been helpful in solving this problem. Remember, momentum and wavelength are inversely related! Understanding the significance of de Broglie's hypothesis is crucial.
