In a Rutherford scattering experiment when a projectile of charge and mass approaches a target nucleus of charge and mass , the distance of closest approach is . The energy of the projectile is:

Answer: (1)

Solution

At the distance of closest approach the projectile stops momentarily, so its entire kinetic energy has been converted into electrostatic potential energy: \dfrac{1}{4πε_0}$Missing argument for \dfrac\dfrac{
