A particle of mass M1 and charge z1 possess initial velocity u, when it is at a large distance from the nucleus of an atom having atomic number z2. At the distance of closest approach, the kinetic energy of particle is completely converted to potential energy. Mathematically, 21M1u2=4πε01r0z1z2 So the energy of the particle is directly proportional to z1z2.
In a Rutherford scattering experiment when a projectile of charge Z_1 and mass M_1 approaches a target nucleus of charge Z_2 and mass M_2, the…
