There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An particle carri?
There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An alpha particle carries a charge of +2e. In a scattering experiment, an alpha particle, heading directly toward a nucleus, will come to a halt when all the particle's kinetic energy is converted to electric potential energy. In such a situation, how close will an alpha particle with a kinetic energy of 5.0 x 10^-13 J come to a nucleus with atomic number Z = 79?
ε₀=8.854e-12 F/m, Ek=5e-13 J
Q₁=Zq, Q₂=2q, where q=1.6e-19 C is an elementary charge
Conservation of energy:
initial kinetic energy = final electrostatic potential energy
Ek=Ep=Q₁Q₂/(4πε₀r)
r=Q₁Q₂/(4πε₀Ek)
r=79*2*(1.6e-19)²/(4π*8.854e-12*5e-13)
r=7.27e-14 m
