Mobility, μ =(vd/E) =(7.5 × 10-4/3 × 10-10) =2.5 × 106

Q. A charged particle having drift velocity of $7.5 \times 1 0^{- 4} m s^{- 1}$ in an electric field of $3 \times 1 0^{- 10} V m^{- 1}$ , has a mobility in $m^{2} V^{- 1} s^{- 1}$ of:

$2.25 \times 1 0^{15}$

$2.5 \times 1 0^{6}$

$2.5 \times 1 0^{- 6}$

$2.25 \times 1 0^{- 15}$

Mobility, $μ = \frac{v _{d}}{E}$
$= \frac{7.5 \times 1 0 ^{- 4}}{3 \times 1 0 ^{- 10}}$
$= 2.5 \times 1 0^{6}$
