A5.12 A pendulum bob of mass m is attached to the ceiling by a thin wire of length L. The bob moves at constant speed in a horizontal circle of radius R, with the wire making a constant angle ß with the vertical. The tension in the wire A. is greater than mg. B. is equal to mg. C. is less than mg. D. could be two of the above, depending on the values of m, L, R, and ß. E. could be all three of the above, depending on the values of m, L, R, and ß. © 2020 Pearson Education, Inc.

Could you possibly include a picture of the written solution, the transcription gets a bit confusing! Thank you :)

I want to ask the question(a)'s answer ,why the positive root isn't physically valid .

Hello, I have a physics assignment and wanted to get help with the answers. I was told to repost the question to get the remaining sub parts done. I accidentally posted a photo a few minutes ago without the instructions I just need the bottom four completed.
