Calculate the uncertainty in the momentum of an electron if it is confined to a linear region of length ` 1xx10^(-10)` metre.

Text Solution

Verified by Experts

According to uncertainty principle,
`Deltax. Delta p=(h)/(4 pi) or Delta p=(h)/(4 pi Deltax) , Deltap=((6.626 xx10^(-34)kg m^(2)s^(-1)))/(4xx3 .143 xx (10^(-10)m))=5.27 xx 10^(-25) kg ms^(-1)`
