Question

Suppose an alpha particle accelerated by a potential of V volt is allowed to collide with a nucleus whose atomic number is Z, then the distance of closest approach of alpha particle to the nucleus is ______.

पर्याय

• 14.4 \[\frac{\text{Z}}{\text{V}}\]Å

• 14.4 \[\frac{\text{V}}{\text{Z}}\]Å

• 1.44 \[\frac{\text{Z}}{\text{V}}\]Å

• 1.44 \[\frac{\text{V}}{\text{Z}}\]Å

Answer 1

Suppose an alpha particle accelerated by a potential of V volt is allowed to collide with a nucleus whose atomic number is Z, then the distance of closest approach of alpha particle to the nucleus is 1.44 \[\frac{\text{Z}}{\text{V}}\]Å.
