Question

Gravity is a long-range force proportional to the masses of the interacting bodies. Physicists have long searched to see if there might be a long-range force that is proportional to baryon number. Think about the composition of atoms and propose a “thought experiment” that could detect such a force.

 

 

Answer 1

Quarks: It is the fundamental particle of atom and has charge value either (-1/3) or (2/3) times the elementary change (e).

 

Baryon Number is additive quantum number of a system.

B = 1/3(nq – n-q)

 

Here, B is Baryon number, nq is the number of quarks, n-q is the number of antiquarks.

 

Gravitational force is defined as the attractive force between two objects that are inversely proportional to the square of distance between them and proportional to the product of their masses.

 

F = GN m1m2/r2

 

 

Here, GN is universal gravitational constant and m1, m2 are masses of objects.

 

Gravitational force is directly proportional to their masses and objects are composed of quarks that is the most fundamental particles of atom. Baryon number is associated with quarks so, we can say that masses are directly proportional to baryon number. Hence gravitational force is proportional to baryon number.

 

Hence, long range force that is gravitational force is proportional to baryon number.

Hence, long range force that is gravitational force is proportional to baryon number.
