Calculate the unceertainty in position of an electron if the uncertainty in its velocity is `5.7 xx 10^(5) m s^(-1), h = 6.6 xx 10^(-24) kg m^(2) s^(-1)` mass of electron `= 9.1 xx 10^(-13 kg) `

Answer

A, D

Explanation

`1 xx 10^(10)m`
Hint: `Delta x - Delta p = (h)/(4pi) `
or` Delta x - Delta v = (h)/(4pi) `
`Delta x = (h)/(4pi m Delta v) `
`m_(s) = 9.1 xx 10^(-27) g Delta V = 5.7 xx 10^(3) ms^(-1)`
