Understanding Pulleys: Velocity Calculations for Three Blocks | Pathfinder Question Q 34 | IIT JEE

0:00 34. Three blocks A, B, and C are suspended with the help of three pulleys and two threads with equal horizontal separation between adjacent blocks. Initially, the blocks are held at rest at the same level and then released. The blocks move in such a way that they always remain in a straight line. If at an instant, the block B is observed moving downwards with a velocity of 4 cm/s relative to block A, find the velocities of all the blocks at this instant.
