Question

A charged particle is moving in an electric field of $3\times 10^{-10}V{m}^{-1}$ with mobility $2.5\times 10^{-6}{m}^2/v/s$, its drift velocity is

• A. $2.5\times 10^{4}m/s$
• B. $1.2\times 10^{-4}m/s$
• C. $7.5\times 10^{-4}m/s$
• D. $8.33\times 10^{-4}m/s$

Answer 1

Answer: (C)

$\mu =\frac{V_d}{E}\Rightarrow V_d=\mu E$
