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

Drift speed $(v)$ varies with the intensity of electric field $(\mathrm{E})$ as per the relation
  1. $v \propto \mathrm{E}$
  2. $v \propto \frac{1}{\mathrm{E}}$
  3. $v \propto \mathrm{E}^2$
  4. $v \propto \mathrm{E}^{-2}$

Solution

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