The mobility ((mu)) of electrons can be calculated using the relation between drift velocity ((v_d)), electric field ((E)), and mobility, given by the equation:

[

mu = frac{v_d}{E}

]

Given:

– Drift velocity, (v_d = 23) units

– Electric field, (E = 11) units

Substituting the given values into the equation, we get:

[

mu = frac{23}{11} = 2.09 , text{units}^2/text{unit time}

]

Therefore, the mobility of the electrons is (2.09) units squared per unit time.

b

Explanation: The mobility is defined as the drift velocity per unit electric field. Thus μe =

vd/E = 23/11 = 2.1 units.
