# NEET Physics Atoms Questions Solved

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 distance of closest approach is ${r}_{0}$. The energy of the projectile is

(a) directly proportional to ${M}_{1}×{M}_{2}$

(b) directly proportional to ${Z}_{1}{Z}_{2}$

(c) inversely proportional to ${Z}_{1}$

(d) directly proportional to mass ${M}_{1}$
