In Bohr's model of `H_(2)` atom, the electrons move around the nucleus in a circular orbit of radius `5xx10^(-11)` m. Its time period is `1.5xx10^(-16)` s, the current associated with electron motion is

Options

A. zero
B. `1.6xx10^(-19)`A
C. 0.17 A
D. `1.07xx10^(-3) A`

Answer

D

Explanation

`r=5xx10^(-11)m, t=1.5xx10^(-16)s`
`i=(q)/(t)=(1.6xx10^(-19))/(1.5xx10^(-16)) implies I = 1.07xx10^(-3)A`
