The uncertainity in the positions of an electron and proton is equal, the ratio of the uncertainities in the velocity of an electron and proton is

A

`10^(3) :1`

B

`1:1836`

C

`3672:1`

D

`183:1`

Text Solution

Verified by Experts

The correct Answer is:
D
`(Delta x_(e).m_(e). Deltav_(e^-) )/(Delta x_(p).m_(p). Delta vp)=1 " "(Delta v_e)/(Delta vp)=(m_p)/(m_e)`
