Date: 2021-08-15

DON'T MISS THE 4 PRACTICE PROBLEMS ON ROLLING/RIGID OBJECTS AND DIFFERENT SITUATIONS OF ICR / IAOR AT THE END OF THE VIDEO. 
Q : A uniform rod of mass m and length l slides without friction along a vertical wall and horizontal floor as shown. Gravity and the contact forces from wall and floor are the only forces acting on the rod. At the instant shown, direction of angular velocity of rod  is given as in diagram. A,B are end points of the rod and A',B' are points on the wall and floor in contact with A and B at this constant . C is centre of mass of the rod.
 1. Which of the following is not applicable ? ( is the torque due to real forces)
 (a) equation about an axis perpendicular to the diagram and attached to A
 (b) equation about an axis perpendicular to the diagram and attached to C
 (c) about an axis perpendicular to the diagram and attached to B
 (d) about an axis perpendicular to the diagram and attached to B'
 
LEARN THE BEST WAY TO COUNTER THESE PROBLEMS IN EXAM CONDITIONS. WHAT'S THE SHORTEST WAY TO COUNTER THESE PROBLEMS?  THE ANSWER LIES IN THE LUCID EXPLANATION OF CONCEPT/SOLUTION IN THE VIDEO . IN THIS VIDEO WE PRESENT AN EXAM ORIENTED APPROACH FOR ROTATION BUILD - 3 CHAPTER - 5 AND IMPULSE AND MOMENTUM CHECK-20 CHAPTER-4 SOLVED FROM THE BOOK "PATHFINDER PHYSICS"👇.THE FOUR PRACTICE PROBLEMS ARE CHOSEN CAREFULLY IN INCREASING LEVEL OF DIFFICULTY FROM JEE MAINS , ADVANCED AND OLYMPIADS . WHAT WE CAN EXPECT IN FUTURE ON THIS TOPIC ?
