NEET Physics (general) MCQ Question
Which of the following statements about the behavior of electrons in a conductor are correct?
Electrons collide randomly with atoms, affecting their average velocity.
Electrons maintain a steady velocity between collisions without any acceleration.
The average velocity of electrons in a conductor is always zero.
Collisions of electrons occur at regular intervals, leading to uniform acceleration.
Correct Answer
Detailed Explanation
Statement A is correct as it reflects the random nature of electron collisions and their effect on average velocity. Statement B is incorrect because electrons do accelerate between collisions. Statement C is misleading since it implies that the average velocity cannot be non-zero during current flow. Statement D is false because collisions do not occur at regular intervals.
