They don't. Well, they do in flat spacetime in the absence of an external force, but it's not a peculiar property of cathode rays; everything does that.
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
In the absence of magnetic fields, cathode rays will continue to travel in a straight line. Magnetic fields can be used to deflect or focus cathode rays, but without these fields, the electrons will not be influenced and will travel unaffected.
Light rays travel in straight lines due to the principle of the shortest path, known as Fermat's principle. Light travels along the path that minimizes the time it takes to travel from one point to another. This results in light rays following straight lines in a uniform medium.
Light rays travel in straight lines called rays or beams. They propagate by transferring energy and momentum through particles or fields, such as photons in a vacuum or electromagnetic waves in a medium. Light rays can be reflected, refracted, or absorbed when interacting with different materials.
All rays of light are a form of electromagnetic radiation that travel in straight lines at a constant speed in a vacuum, and they can be reflected, refracted, and absorbed.

Cathode rays produce a sharp shadow of an object because they travel in straight lines and can only pass through openings in obstacles. When an object is placed in the path of cathode rays, the rays are blocked by the object, creating a distinct shadow where the rays are unable to pass through. This phenomenon is due to the wave-particle duality of cathode rays.

cathode rays can't travel in air
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
Cathode rays in a vacuum would travel until stopped (or deflected by an electromagnetic field).
why it is necessary to decrease the pressure in the discharge tubbe to get cathode rays
To remember this think of you are looking directly at a building a car crash happens behind this building. You know this from the sound produced that can travel in all directions past the building. You cannot see it because as light dose not bend under normal circumstances and will only travel in straight lines. Even if reflected using a combination of mirrors it still travels in straight lines.
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
