strong nuclear force

Question 1

STRONG NUCLEAR FORCE

Answer 1

:this force is extremely strong in the short range but disappears at distances greater than the diameter of a nucleus. it acts as a glue, holding the nucleus together

Question 2

relative size of electromagnetic and SNF

Answer 2

[insert diagram]

Question 3

interpretation of diagram (SNF)

Answer 3

• the SNF is extremely strong and repulsive at very short range (<0.5fm)
• very strong and attractive about the typical distance between nucleons
• beyond 3fm it is effectively 0

Question 4

interpretation of diagram (electromagnetic force)

Answer 4

• between protons gets less the further apart the protons are
• never 0
• always repulsive

Question 5

interpretation of diagram

Answer 5

• at extremely short distances both forces repel and keep the nucleons apart
• at typical nucleon separation the SNF attracts nucleons together very strongly
• at distances greater than 3fm, electromagnetic force repels the protons from each other
