हिन्दीA charged particle having drift velocity of \( 7.5 \times 10^{-4}\text{ m s}^{-1} \) in an electric field of \( 3 \times 10^{-10}\text{ Vm}^{-1} \), has a mobility in \( \text{m}^2\text{ V}^{-1}\text{ s}^{-1} \) of:
Correct answer · Option 1
\( 2.5 \times 10^{6} \)
Explanation
Mobility \( \mu = \frac{v_d}{E} = \frac{7.5 \times 10^{-4}}{3 \times 10^{-10}} = 2.5 \times 10^{6}\text{ m}^2\text{ V}^{-1}\text{ s}^{-1} \).
