Correct Answer - A
We know that `alpha` particle carries two units of positve charge and four units of mass In `alpha` decays charge number of parent nucleus decreses by 2 units Alos mass number reduces by four units.

which a `U^(238)` nucleus original at rest , decay by emitting an alpha particle having a speed `u` , the recoil speed of the residual nucleus is

Correct Answer - C `U^(238) rarr U^(234)+._(2)He^(4)` Let recoil speed be V then by COLM `234 V=4uimplies V=(4u)/234`

A stationary radioactive nucleus of mass 210 units disintegrates into an alpha particle of mass 4 units and residual nucleus of mass 206 units. If the

Correct Answer - B Momentum remains constant, `K=(p^(2))/(2m)or Kprop(1)/(m)implies(K_(n))/(K_(alpha))=(m_(alpha))/(m_(n))=(4)/(206)=(2)/(103)` `therefore` Kinetic energy of the residual nucleus `K_(n)=((2)/(103))K_(alpha)=((2)/(103))E`

(A) in alpha particle scattering number of alpha paritcle undergoing head on collision is small. (R) small fraction of the number of incident particle

Correct Answer - B the number of alpha particles undergoing head on collision is small. This in turn, imlies that the mass of the atom is concentrated in a small volume.
