Calculate the uncertainty in velocity of...

Calculate the uncertainty in velocity of an electron if the uncertainty in its possible is of the order `+-12` pm.

Text Solution

Verified by Experts

According to uncertaintly principle, `Deltax*mDeltav=h//4pi`
`therefore Deltav=(6.626xx10^(-34))/(4xx3.14xx(9.11xx10^(-31))xx(12xx10^(-12)))`
[`because` Mass of electron`=9.11xx10^(-31)kg & 1 "pm"=10^(-12)m]`
`=4.82xx10^(6)m*s^(-1)`
