What is the uncertainty in velocity of an electron if the uncertainty in its position is `10^(-10) m`? Mass of the electron is `9.1 xx 10^(-31) kg and h = 6.6 xx 10^(-34) m^(2) s^(-1)`?

Answer

A, D

Explanation

`5.77 xx 10^(5) m s^(-1)`
Hint: `Delta x - m- Delta v = (h)/(4pi) `
` :. Delta v = (h)/(4 pi-m- Delta x)`
