Mam did you explain this questions,
1. Two points charges +4e and +e are fixed a distance 'a' apart. where should a third point charge q be placed on the line joining the two charges so that it may be in equilibrium? In which case the equilibrium will be stable and in which unstable?
2. Two free points charges +4e and +e are fixed a distance 'a' apart. where should a third point charge q be placed between them such that the entire system may be in equilibrium? what should be the magnitude and sign of q? what type of equilibrium will it be?
What is main difference between this questions and explain the solution for this questions.

This video solved a problem for me: who is Kathy? She's an AP physics teacher! Of course she is.
I am loving the science history, especially the inclusion of women. Keep up the great work. I'm looking forward to Emmy Noether.
Tiny correction in tip 4: At 18: 27 you probably meant to say equilateral triangle, and cosine of 30 degrees is sqrt(3)/2.
Thanks for all the wonderful content.

Kathy please explain why is everything in nature described as sine wave like? And to understand that light is a wave, it is very difficult to picture, also light being emitted when an electron jumps to a lower shell, why is that producing a fluctuating electric field, which generates the magnetic field and for that to continue forever, why does it not dissipate?

I enjoyed this! My school is too rural and small to have AP Physics, but I do teach Physics and Coulomb's Law. I also teach Chemistry. I love how you mixed dimensional analysis (which I heavily emphasise in my Chemistry class) with Physics. Very fun, and my kids will understand it this way!

Great explanation on math, but can you explain the x direction a little more. I understand the law of charges, it is the X notation that is new to me. It looks like the x direction notation did not change. Thank you for a great video.

Before I make a comment, I like to read all of the other comments so that I will not be redundant. So, I am disappointed to be the seventh person to notice. You have been waving at us with your left arm.

This is the same as computing the apparent wind from the true wind and boat speed and direction. Hah, Kathy, you werent going to catch me using a scalar value such as speed as a vector.

Left handed instructors are better on the chalk board. Pythagoreans theorem is just as special case of the law of cosines.
