The de-broglie wavelength associated with a mass of 1kg having K.E. 0.5 J is :

A

`6.626 xx 10^(-34)m`

B

`13.20xx10^(-34)m`

C

`10.38xx10^(-34)m`

D

`6.626xx10^(-34)` Å

Text Solution

Verified by Experts

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