# 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.

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