    find the error in the calculation FE4 Two identical uniform thin rigid rods are held together at one end with an electromagnet. One of the rods is attached to a fixed pivot point, around which the magnetic two rods are rotating at a constant rate (there is no gravity present here). Suddenly the connector electromagnet is tumed off, and the rod not attached to the pivot flies away. Find the percentage change in kinetic energy of the system before and...
