If uncertainty in velocity is`6.62xx10^(-2)m//sec` . For a particle of mass of `(0.05)/pigm`. Its uncertinty in position may be

A

`0.5xx10^(-14)`

B

`10^(-15)`

C

`0.8xx10^(-15)`

D

`0.5xx10^(-10)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta"x".(6.662xx10^(-12))ge(6.62xx10^(-34))/(4xxpixx((0.05xx10^(-3))/(pi)))`
`Delta"x"ge (10^(-19))/(0.2)" "rArrDelta"x"ge0.5xx10^(-18)`
