Calculate the uncertainty in the velocity of anelectron when the uncertainty in its positionis `1.012 xx 10^(-12) m`

Explanation

According to Heisenberg.s uncertainty priciple
` Delta xx xx Delta p ge (h)/( 4 pi)`
` Delta p = Mdelta V `
` therefore M Delta v ge (h)/( 4 pi Delta x )`
` Delta v ge (h)/( 4 pi m Delta x )`
molar of an electrons =` 9.1 xx 10 ^(-31) kg `
` pi = 3.142 ` or ` (22)/(7)`
` Delta x = 1.012 xx 10 ^(-12) ` m
` therefore Delta v = ( 6.626 xx10 ^(-34) Js ) /( 4xx 3.142 xx (9.1 xx10 ^(-31) kg ) xx ( 1.012 xx 10 ^(-12) m)) " " ( j = kg m^2 s^(-1))`
` Delta V = 5.72 xx 10 ^(7) ms^(-1)`
