Question

Drift velocity vd varies with the intensity of electric field as per the relation:- (A) vd propto E (B) vd propto (1/E) (C) vd= constant (D) vd propto E2

Tardigrade Admin · Accepted Answer

vd=(e/m)× (V/1)τ or vd=(e/m)⋅ (E 1/1)τ[∵ V = E 1] ∴ vd propto E

Q. Drift velocity $v_{d}$ varies with the intensity of electric field as per the relation:-

$v_{d} \propto E$

$v_{d} \propto \frac{1}{E}$

$v_{d} =$ constant

$v_{d} \propto E^{2}$

$v_{d} = \frac{e}{m} \times \frac{V}{1} τ$ or $v_{d} = \frac{e}{m} \cdot \frac{E 1}{1} τ [∵ V = E 1]$
$∴ v_{d} \propto E$

Q. Drift velocity vd​ varies with the intensity of electric field as per the relation:-

vd​∝E

vd​∝E1​

vd​= constant

vd​∝E2
