The speed at which current travels, in a conductor, is nearly

A

300 m/s

B

`3xx10^(5)m//s`

C

`3xx10^(6)m//s`

D

`3xx10^(8)m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
`I=(q)/(t)=(e)/(t)=(ev)/(2 pi r)`
`= (1.6xx10^(-19)xx2.18xx10^(6))/(6.28xx0.53xx10^(-10))`
`=1.048xx10^(-3)A`
