Thin Ring Electric Field

[@Mr_Reggie]

I watched this video the day before a test and the FRQ was exactly the same as what this video covered. Thanks Flipping Physics!

You are a legend. Just in case you forgot! About to start my Physics C Mechanics class tomorrow!

When teaching my students, would it be sufficient if they understand why we can approximate the ring as a point charge Q in the middle of the ring without the integration?

[@andrewjustin256]

I have a question: will the negative charge move around the ring 💍 passing through the center side, or will it move up and down the horizontal position of the ring?

Sir it's 9.56 pm in india 🥲 and I'm studying at this time 😅😅😃

[@FlippingPhysics]

Lovely. It is 12:30 PM in the USA and I am about to eat lunch. Enjoy the studies!

Amazing video once again

[@FlippingPhysics]

Thanks for the love!

Mr. P, why does the negative point charge oscillate in simple harmonic motion when the rod is positive? Instead, I assume it should be attracted to it and clung to the rod completely.

[@FlippingPhysics]

The net force in the y-direction on the negative point charge is zero when it is along the horizontal axis of the ring. Perhaps you missed that it's a ring and not a rod?

[@andrewjustin256]

​@@FlippingPhysics Even if we assume it is a ring, there should be a simple attraction, but still why is it in a SHM?

Man I thought I was out of the woods from mechanics last year...
