The momentum of a particle having ade-Broglie wavelenth of 10^(-17)m is (h=6.625xx10^(-34)Js)

Answer»

`6.625xx10^(-17)kgms^(-1)`
`3.3125xx10^(-7)kgms^(-1)`
`13.25xx10^(-17)kgm^(-1)`
`26.5xx10^(-7)kgms^(-1)`

SOLUTION :`LAMDA=h/p` or `p=h/(lamda)=(6.625xx10^(-34))/(10^(-17))`
`=6.625xx10^(-17)kgms^(-1)`
