If the net torque acting on a system is zero, what can we infer about the system’s angular momentum?

This question tests the conservation of angular momentum under zero net torque.

Develop a set of multiple-choice questions (MCQs) for CBSE Class 11 Physics, Chapter 6: “System of Particles and Rotational Motion,” based on the NCERT syllabus for the 2024-2025 academic year. The MCQs should comprehensively cover core topics such as the center of mass, torque, angular momentum, rotational dynamics and equilibrium. Include both theoretical and numerical problems that assess students’ understanding of concepts as well as their ability to solve practical problems. The questions should vary in difficulty, ensuring a mix of basic, intermediate and advanced-level questions to cater to a range of learners. It is important to ensure that each question is clearly phrased and concise, allowing students to focus on the core concepts without ambiguity. Additionally, the content should be strictly aligned with NCERT guidelines to ensure relevance and accuracy, helping students in both their exam preparation and in strengthening their grasp of fundamental principles related to rotational motion and systems of particles.
