An alpha nucleus of energy (1)/(2)m nu^(...

An alpha nucleus of energy `(1)/(2)m nu^(2)` bombards a heavy nucleus of charge `Ze` . Then the distance of closed approach for the alpha nucleus will be proportional to

A

`(1)/(v)`

B

`(1)/(Ze)`

C

`v^2`

D

`(1)/(m)`.

Text Solution

Verified by Experts

The correct Answer is:
D

`(1)/(2) mv^(2)=(1)/(4pi epsilon_0)((2e)(ze))/( r)`
`K.E. =+(13.6 Z^2)/(n^2)`
`therefore K.E.=T.E`
