# Time period of SHM

What i am doing wrong in this problem? Here A is the COM and P is the bottom most point about which i calculated torque so as to prevent consideration of (friction for without slipping conditions). C is centre of cylinder shell. Using 1 and 2 i am getting answer to be 2pi√2R/g . I got the inspiration to do this problem using bottom most point as from this problem "20" in the link:: problems: https://www.slideshare.net/mobile/miranteogbonna/soal-latihan1mekanika , solutions: https://www.slideshare.net/mobile/miranteogbonna/jawaban-soallatihan1mekanika

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
• Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

In the first picture, what is the correct option? According to me, the answer should be option 1.
