Strong Nuclear Force 2.1.3

Question 1

what forces are in the nucleus

Answer 1

-Repulsive electrostatic forces between protons due to their positive charge

-Attractive gravitational forces due to the mass of the nucleons

Question 2

what is the weakest of the fundamental forces

Answer 2

Gravity

Question 3

what are the 4 fundamental forces

Answer 3

• strong force
  -weak force
  -electromagnetic force
  -gravity

Question 4

what does the electromagnetic force cause

Answer 4

protons to repel each other

Question 5

what would happen if there was no strong nuclear force

Answer 5

the nucleus would not hold together

Question 6

what does strong force do

Answer 6

keeps the nucleus together and stable

Question 7

what is strong force for

Answer 7

protons and neutrons

Question 8

what is electromagnetic force for

Answer 8

protons

Question 9

what is strong nuclear force

Answer 9

an attractive force acting between all nucleons which is stronger than the electrostatic force

Question 10

what are quarks

Answer 10

The strong nuclear force acting between particles

Question 11

what are protons and neutrons made up of

Answer 11

quarks

Question 12

when is strong force highly repulsive at separations

Answer 12

below 0.5fm

Question 13

when is strong force very attractive up to a nuclear seperation

Answer 13

3.0fm

Question 14

when does the maximum attractive value occur

Answer 14

around 1.0fm

-which is a typical value for nucleon separation

Question 15

what is the the equilibrium position, where the resultant force is zero.

Answer 15

0.5fm

Question 16

what range does strong nuclear force have

Answer 16

a very small range in comparison to the other fundamental forces

(from 0.5 to 3.0fm)

Question 17

what is electrostatic force influenced by which strong force is not

Answer 17

charge
