0.5 gm particle has uncertainity of `2xx10^(-5)` m find the uncertainty in its velocity`(m//s)`

A

`3.0xx10^(33)`

B

`5xx10^(-27)`

C

`4xx10^(-19)`

D

`4xx10^(-10)`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaV.DeltaV=(h)/(4pim)`
`DeltaV=(0.527xx10^(-34))/(5xx10^(-4)xx2xx10^(-5))`
`=5.2xx10^(-27)`
