An alpha particle (mass = 4 u) has a head-on, elastic collision with a nucleus (mass = 104 u) that is initially at rest. What percentage of the kinetic energy of the alpha particle is transferred to the nucleus in the collision?

found in the nucleus

has mass of one amu

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
