In the (i) absence of electric field, and in the (ii) presence of electric field, the paths of electrons between successive collisions with the positive ions of the metal, are
- A (i) Straight line, (ii) straight line
- B (i) Curved, (ii) straight line
- C (i) Curved, (ii) curved
- D (i) Straight line, (ii) Curved in general
Answer & Solution
Correct Answer
(D) (i) Straight line, (ii) Curved in general
Step-by-step Solution
Detailed explanation
In the absence of an electric field: Electrons move with constant thermal velocity, so their path between two successive collisions is a straight line. In the presence of an electric field: The electric force \(F=-e E\) continuously accelerates the electrons, making their…
