In Rutherford scattering experiment, `alpha`-particles scattered at angle `theta `by a target, then which of the following is correct for Impact parameter "b" ?

A

`b prop sec^2 theta `

B

`b prop sec^3 theta `

C

`b prop tan ""((theta)/(2))`

D

`b prop cot ""(theta /2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`b= ( 2Ze^2 cot ""(theta)/(2))/(4 pi epsi_9 mv _(0)^(2)) " " b prop cot "" theta / 2`
