on the ground directly beneath the sphere, the normal force, gravity, and the friction force all pass through this point or lie along the line of action. Therefore, the net external torque about point is zero throughout the entire motion. physics galaxy discussion questions solutions

It produces a torque about the center of mass that increases the angular velocity ( Which (e

For students navigating the turbulent waters of competitive exams like the JEE (Joint Entrance Examination) and NEET, the name Physics Galaxy is nothing short of legendary. Ashish Arora’s magnum opus isn't just a textbook; it is a philosophy. However, the true goldmine within this series lies in the —a section designed not just to test memory, but to ignite analytical thinking. It produces a torque about the center of
