Type: MCQ-diagram based-Medium-Class 12
Consider a diagram of an electron moving between two points A and B through repeated collisions and straight-line travel in the presence of an electric field. Which of the following best describes the average velocity of the electrons immediately after a collision?
A
The average velocity is zero due to random direction.
B
The average velocity is maximum due to acceleration.
C
The average velocity equals the drift velocity.
D
The average velocity is constant throughout the motion.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the average velocity of electrons immediately after a collision is zero because the direction of their velocity is completely random.
