Uncertainty in position of electron is 10^(-10) m. uncertainty in its momentum will be…….kgms^(-1).(h=6.62xx10^(-34) J-s)

Answer»

`1.05xx10^(-24)`
`1.03xx10^(-24)`
`1.06xx10^(-24)`
`1.08xx10^(-24)`

Solution :From Heisenberg uncertainty PRINCIPLE,
`Deltax.DELTAP=(h)/(lpi)`
`Deltap=(h)/(2piDeltax)=(6.62xx10^(-34))/(2xx3.14xx10^(-10))`
`therefore Deltap=1.05xx10^(-24)kg MS^(-1)`
