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

  1. A \(v \propto \mathrm{E}\)
  2. B \(v \propto \frac{1}{\mathrm{E}}\)
  3. C \(v \propto \mathrm{E}^2\)
  4. D \(v \propto \mathrm{E}^{-2}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(v \propto \mathrm{E}\)

Step-by-step Solution

Detailed explanation

The drift speed is given by \(v_d=\left(\frac{c E}{m}\right) و \Rightarrow v_d \propto E\)
