Two Observers and the Motion of Protons

In summary, the conversation discusses the scenario of two protons traveling at the same velocity parallel to each other, and how different observers perceive their motion. One observer, who is also traveling at the same speed, sees the protons as stationary and only experiences the electrical attraction between them. However, a stationary observer sees the protons as moving and notices the influence of their magnetic fields on each other. The conversation ends with a question about the difference in the effect of the electric force due to the different time intervals.

hello, this is a question from the book that i got no idea on it

'When two proton are traveling at same velocity parallel to each other, like this (respect to groung)

proton A >>>
proton B >>>

an observer is also travel at the same speed along their path. according to him, two proton are stationary, so the only force is the electrical attraction

Another observer who is stationary will observe two proton moving, both create magnetic field which influence the motion of the other proton

What do you say?

I thought the two observer are both in inertial frame, therefore should applied the same law. but the situation is different to that? i am totally confused.

Can anyone help me? thanks very much

I think it's that the time interval is also different,so the effect of the electric force is defferent.You can calculate it.
 

FAQ: Two Observers and the Motion of Protons

What is the motion of protons?

The motion of protons refers to the movement of these positively charged particles within an atom or a larger particle, such as a proton beam. Protons can have different types of motion, including translational, vibrational, and rotational.

How do two observers perceive the motion of protons differently?

The motion of protons can be observed differently by two observers depending on their relative positions and velocities. This is due to the effects of relativity, as described by Einstein's theory of special relativity.

What is the role of the observer's frame of reference in the motion of protons?

The observer's frame of reference is crucial in understanding the motion of protons. It is the specific point of view or perspective from which an observer measures and describes the motion of objects. Different frames of reference can lead to different observations and perceptions of the same motion.

Can the motion of protons be affected by external forces?

Yes, the motion of protons can be influenced by external forces such as electric and magnetic fields. These forces can accelerate, decelerate, or change the direction of the protons' motion.

What are some practical applications of studying the motion of protons?

Studying the motion of protons has many practical applications, including in medical imaging and treatments such as proton therapy, in nuclear power and particle accelerators, and in understanding the behavior of matter at the atomic and subatomic level.
