The position of both, an electron and a helium atom, is known within 1.0 nm. Further, the momentum of the electron is known within 5.0 xx 10^(-26) kg ms^(-1). The minimum uncertainty in the measurement of momentum of helium atom is

Answer»

`50 KG ms^(-1)`
`5.0 xx 10^(-26) kg ms^(-1)`
`80 kg ms^(-1)`
`80 xx 10^(-26) k ms^(-1)`

SOLUTION :`Deltax Delta p =` const. As `Delta X` is same, `Delta p` will be same
