Question

Drift speed \( v \) varies with the intensity of the electric field \( E \) as per the relation

• A. \( v \propto E \)
• B. \( v \propto \frac{1}{E} \)
• C. \( v \propto E^2 \)
• D. \( v \propto E^{-2} \)

Hint:

Drift speed is directly proportional to the applied electric field in a conductor.

Answer 1

The Correct Option is A

Drift velocity is given by: \[ v_d = \mu E \] where \( \mu \) is mobility. Clearly, \[ v_d \propto E \] Thus, the correct answer is \( v \propto E \).
