Question

In the Bohr's model of hydrogen atom the electron moves around the nucleus in a circular orbit of radius 5 × 10^-11m. Its time period is 1.5 × 10^-16. The current associated with electron motion is:-

Options

• zero

• 1.6 × 10^-19A

• 1.07 × 10^-3A

• 0.017A

Answer 1

1.07 × 10^-3A

Explanation:

Current I = `"Charge"/"Time" = e/T`

= `(1.6 xx 10^-19)/(1.5 xx 10^-16)`

= `1.07 xx 10^-3`A.
