If the velocity of the electron in Bohr'...

If the velocity of the electron in Bohr's first orbit is `2.19xx10^(6) m s^(-1)`, calculate the de Broglie wavelength associated with it.

A

`2.19xx10^(-6)`m

B

`4.38xx10^(-6)`m

C

`3.32xx10^(-10)`m

D

`3.32xx10^(10)`m

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda=h/(mv)=(6.626xx10^(-34)Js)/(9.11xx10^(-31)kgxx2.19xx10^(6)ms^(-1))
=3.32xx10^(-10)m`
