Question 644: Current Electricity

Question

A charged particle having drift velocity 7.5$$ 	imes $$10-4 ms-1 in an electric field of 3$$ 	imes $$10-10 Vm-1 has a mobility in m2 V-1s-1 of :

Accepted Answer

The relation between the mobility and drift velocity is,
Mobility, $$\mu  = {{{\upsilon _d}} \over E}$$
$$ = {{7.5 	imes {{10}^{ - 4}}} \over {3 	imes {{10}^{ - 10}}}}$$
$$ = 2.5 	imes {10^6}{m^2}{V^{ - 1}}{s^{ - 1}}$$

Answer

2.5 $$ 	imes $$106

Answer

2.5 $$ 	imes $$10-6

Answer

2.25 $$ 	imes $$10-15

Answer

2.25 $$ 	imes $$1015

Current Electricity

A charged particle having drift velocity 7.5$ \times 10-4 ms-1 in an electric field of 3 \times $10-10 Vm-1 has a mobility in m2 V-1s-1 of :
