The average time between two successive ...

The average time between two successive collision of an electron is `3.64xx10^(-8)s`. Its mobility is

A

`6.4xx10^(3)m^(2)V^(-1)S^(-1)`

B

`640 m^(2) m V S^(-1)`

C

`6.4 xx10^(3)m V^(-1)S^(-1)`

D

`6.4xx10^(3) m^(2) V S^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`mu=(etau)/(m)=(1.6xx10^(-19)xx3.64xx10^(-8))/(9.1xx10^(-31))`
`=6.4xx10^(3)m^(2)V^(-1)S^(-1)`
