Question

In a Rutherford scattering experiment when a projectile of change `Z_(1)` and mass `M_(1)` approaches s target nucleus of change `Z_(2)` and mass `M_(2)`, te distance of closed approach is `r_(0)`. The energy of the projectile is
A. Directly proportional to mass `M_(1)`
B. Directly proportional to `M_(1) xx M_(2)`
C. Directly proportional to `Z_(1)Z_(2)`
D. Inversely proportional to `Z_(1)`

Answer 1

Correct Answer - C
Energy `=(1)/(4 pi in_(0))(Z_(1)Z_(2))/(r_(0))`
