Question 563: Atoms & Nuclei

Question

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

Accepted Answer

Now energy of the projectile :
= $${1 \over {4\pi {\varepsilon _0}}}{{{z_1}{z_2}} \over r}$$
Therefore energy $$ \propto $$ z
1
z
2

Answer

directly proportional to z

z
2

Answer

inversely proportional to z
1

Answer

directly proportional to mass M
1

Answer

directly proportional to M
