The de Broglie wavelength associated with a ball of mass `1kg` having kinetic enegry `0.5J` is

A

`6.626xx10^(-34)m`

B

`13.20xx10^(-34)m`

C

`10.38xx10^(-21)m`

D

`6.626xx10^(-34)Å`

Text Solution

Verified by Experts

The correct Answer is:
A
`lamda=h/(sqrt(2m(KE)))`
= `=(6.626xx10^(-34))/(sqrt(2xx1xx0.5))=6.626xx10^(-34)`.
