Mass of elements `9.1 xx 10^(-31) kg ` find total uncertainty `(Delta V .Delta x)`
(h = 6.626 `xx 10^(-34) J s)`

Text Solution

Verified by Experts

h= 6.626 `xx10^(34) J s= 6.626 xx 10^(34) kg m^(2) s^(1)`
According to Heisenberg uncertainty
`Delta v .Delta x = (6.626 xx 10^(34) kg m^(2) s^(-1))/(4 xx 3.1416 ,9.1 xx 10^(31) kg )`
`=5.794 xx 10^(3) m^(2) s^(-1)`
Note : this uncertaintly is `0.58 xx 10^(4)` it is useful .so heisenberg principle is useful for electron and particle like electron.
