Question

10) In case of head on collision, when the impact parameter is
minimum, e
rad (where scattering angle for
a particle)
a) π/4
b) π/2
c) 0
d) π​

Answer 1

Answer:

180 deg

Explanation:

Answer 2

Answer:

Option d) π

Explanation:

Impact parameter is defined as the minimum distance between the alpha particle and the nucleus provided that there is no Coulomb repulsion.

Zero impact parameter will occur when the alpha particle is projected on the nucleus and it recoils because of repulsion force parallel to line of motion. In such case, the scattering angle is pi radian or 180 degrees.
