Problem 4. A metal rod of mass mean slide along two parallel horizontal conducting rails without friction. The distance between these rails is l. The movement of the rod is restricted due to the presence of two non-conducting rigid walls W. and W, located at a distance D from each other. A capacitor charged to voltage U, and a resistor Rare connected in series to the rails thorugh the key k. A uniform vertical magnetic field B, such that m > BTC and DBL >> NCU, is switched ou. At the moment when the key was closed, the rod was at rest at the midpoint of the rails between the walls 1. Determine which wall the rod first collides with 2. Determine the speed y before the first collision 3. Determine the speed before the nath collision. Assume that all collisions of the rod with the walls are elastic, D 9 B 39 w w
