What should be the momentum (in gram cm per second) of a particle if its De Broglie wavelength is `1Å` and the value of `h` is `6.6252xx10^(-27)` erg second?

A

`6.6252xx10^(-19)`

B

`6.6252xx10^(-21)`

C

`6.6252xx10^(-24)`

D

`6.6252xx10^(-27)`

Text Solution

Verified by Experts

Given that
`lambda = 1 Å =1 xx10^(-8)cm," "h=6.6252xx10^(-27)` erg second
`"or" " "p=(6.6252xx10^(-27))/(1xx10^(-8))=6.6252xx10^(-19) "gram" cm//sec`.
