in another physics class. basically just gave us the textbook to read. I appreciate your work so far. its great when a proffessor is passionate about teaching.

I loved the demonstration and enjoy your content. I find it extremely helpful and easy to understand. Thanks from a non-student.

really handy content thanks for all lectures greetings from turkey

can you also do a video on electric field due to tetrahedron??

How come you were able to just plug in the r^2? I thought the electric field would have components similar to a couloumb’s law question you worked out in a previous lecture where you used trig to find the components of the force. I mean, I definitely appreciate it, but how come?
