Question

Q.what is the value of Impact Parameter of Alpha particle scattering through an angle of 180 degree??​

Answer 1

.•♫•heya •♫•.

b= Ze^2 cot (theta /2)/4πEo E

when theta = 180°

cot 180°/2

= cot 90° = 0

therefore b = 0

Answer 2

Answer:

For head on collision the scattering angle is 180 degree, therefore the impact parameter is zero>
