uranium 238 nucleus initally at rest with emits an alpha particles with a speed of 1.4 x 7 m/s calculate the recoil speed of the residual nucleus thorium 234

Question

Arun · Answer

Mass∝Mass number or mass=xA,where A is mass number Thorium, m t ​ =234x and mass of alpha particle, m a ​ =4x Velocity of alpha particle is v a ​ =1.4×10 7 m/s and that of thorium is v t ​ Applying momentum conservation, m a ​ v a ​ +m t ​ v t ​ =0(rest) so v t ​ =− m t ​ m a ​ v a ​ ​ , after putting values of masses we get v t ​ =− 117 2v a ​ ​ =−2.4×10 5 m/s Magnitude of velocity of residue nucleus i.e. Thorium nuclei is found to be 2.4×10 5 m/s.
