The mass of electron is `9.11xx10^(-31)`kg. Calculate the uncertainty in its velocity if the uncertainty in position is the uncertainty in position is of the order of `+-10`pm. `(h=6.6xx10^(-34)"kg"m^(2)s^(-1))`.

Answer

`5.76 xx 10^(6) m s^(-1)`

Explanation

`Delta x = 10` pm = `10 xx 10^(-12) m = 10^(-11) m`
