A micorscope using suitable photons is employed an electron in an atom within a distance of ` 0.1 A` . What is the uncetrancity involved in the measurment of its velcity ?

A

`5.79 × 10^(6)ms(–1)`

B

`5.79 × 10^(7) ms^9–1)`

C

`5.79 × 10^(8) ms^(–1)`

D

`5.79 × 10^(5)ms^(–1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaxxxDeltavge(h)/(4pim)`
`thereforeDeltax=0.1Å`
` =1xx10^(-11)m`
`Delta V ge(h)/(4pimxxDeltax)` `DeltaVge (6.626xx10^(-34)J sec)/(4xx3.14xx9.11xx10^(-31)kgxx10^(-11)m)` `Delta ge 5.79xx10^(6) m sec^(-1)`
