How does the Electromagnetic force affect the nucleons?
Causes repulsion between protons
2 of 15
How does the gravitational force affect the nucleus?
Causes attraction between nucleons due to their mass
3 of 15
How does the strong force affect the nucleus?
Cause attraction (repulsion at small distances) between nucleons
4 of 15
What is the attractive range of the strong force?
0.5-3.0 fm
5 of 15
What is a fm in standard form?
1*10^-15
6 of 15
Why does the strong force cause repulsion before 0.5fm?
To stop the nucleons being compressed into a point
7 of 15
What charge is a nucleus?
Positive
8 of 15
Suggest why the strong force must exist
The repulsion caused by the electromagnetic force is far greater than the attraction caused by gravity so there muswt exist another force to stop the nucleus flying apart
9 of 15
What is the range of the electromagnetic force?
infinity
10 of 15
What is the range of gravity?
Infinity
11 of 15
Give a rough idea of the size of a nucleus?
a few fm
12 of 15
How does the intensity of the strong force differ between sub-atomic particles?
It doesn't
13 of 15
Interactions that use the strong nuclear force are called...
strong interations
14 of 15
Which force can you ignore and why?
The gravitational because it is so small compared to the other forces in the nucleus
