Calculate the uncertainty in position of the electron if de-Broglie wavelength associated with electron is `7.2 Å (0.01 %-` error is involved in measurement of velocity ) . ( Mass of electron `= 9.1 xx 10^(-31)kg)`

Explanation

De Broglie wave length of incident electron is
`lamda_(1)=(h)/(sqrt(2meV))" "......(1)`
Shortest wavelength of x ray photon is
`lamda_(2)=(hc)/(Ve)" "......(2)`
`implies(lamda_(1))/(lamda_(2))=(1)/(c)sqrt(((V)/(2))((e)/(m)))=0.1`
