The diagram below shows two particles, both with equal positive charges. The top one (particle 1) is moving to the right at speed v. The bottom is moving up with speed v. The vectors representing those speeds are shown. (Diagram) You know that moving charges will create magnetic fields, and that magnetic fields affect moving charges. Write out the field from particle 2 at the location of particle 1. Write out the field from particle 1 at the location of particle 2
Stellar evolution
We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.
Red Shift
It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.
The diagram below shows two particles, both with equal positive charges. The top one (particle 1) is moving to the right at speed v. The bottom is moving up with speed v. The vectors representing those speeds are shown.

You know that moving charges will create magnetic fields, and that magnetic fields affect moving charges.
Write out the field from particle 2 at the location of particle 1.
Write out the field from particle 1 at the location of particle 2.
Make a diagram that shows those fields. On the same diagram, show the force exerted by particle 2 on particle 1, and the force exerted by particle 1 on particle 2.
Explain your reasoning.
Now, think back to first semester, when we learned the principle of reciprocity (also known as Newton's 3rd Law). Do your forces match up with Newton's 3rd law here? If so, explain. If not, what could be going on?
