If the net external force acting on a system of particles is zero, what can be said about the motion of its center of mass?
This question examines the relationship between external force and the center of mass motion.
Develop a set of multiple-choice questions (MCQs) for CBSE Class 11 Physics, focusing on Chapter 6: “System of Particles and Rotational Motion,” based on the NCERT syllabus for the 2024-2025 academic session. These questions should thoroughly address fundamental concepts such as the center of mass, torque, angular momentum, rotational kinematics, dynamics and equilibrium. Include a balanced mix of theoretical and numerical problems designed to test students’ understanding, application skills and analytical thinking. Questions should range in difficulty to challenge learners at different levels while ensuring they reinforce their grasp of the core topics. The phrasing of each question should be precise and easy to comprehend, ensuring students can focus on problem-solving rather than interpretation. Align the content with NCERT guidelines to maintain curriculum relevance and help students prepare effectively for exams. This approach ensures a comprehensive understanding of rotational motion concepts while enhancing problem-solving skills and exam readiness.

If the net external force is zero, the acceleration of the center of mass is also zero. Hence, it moves with constant velocity according to Newton’s first law of motion. This question related to Chapter 6 physics Class 11th NCERT. From the Chapter 6 System of Particles and Rotational Motion. Give answer according to your understanding.
