Doubt about measurement and units -- scaling an atom up to the size of a pinpoint

  • #1
Homework Statement:
What does it means by scaling the nucleus upto tip of a sharp pin ?
Relevant Equations:
N/A
Actually i was solving a basic physics problem that says : an atom has nucleus size 10^-15m and it is scaled upto the tip of pin 10^-5m . tell the size of atom. I saw this ques already solved here but i just cant understand how size of nucleus can be increased,......

I think it's just asking you to consider a "scale model" of an atom. The factor between the pin diameter and the nucleus diameter is the scale factor you're after, and if you know the diameter of an atom you can then work out the diameter of the "scale model" of the atom by scaling proportionally.

I don't think it actually wants you to increase the size of the nucleus... that would be a little more problematic...
