What is the center of mass of a uniform semicircular ring of radius 𝑅 ?

This question focuses on finding the center of mass of symmetric objects.

Create a set of detailed multiple-choice questions (MCQs) for CBSE Class 11 Physics, Chapter 6: “System of Particles and Rotational Motion,” based on the NCERT syllabus for 2024-2025. Focus on topics like center of mass, torque, angular momentum, rotational dynamics and equilibrium. Include both theoretical and numerical questions of varying difficulty levels to assess students’ understanding and problem-solving skills. Ensure the questions are clear, concise and aligned with NCERT guidelines. This will help students prepare effectively for exams and strengthen their grasp of rotational motion concepts, improving their ability to apply these principles.
