You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below.
Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front.
The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T. The electromagnetic force on the rod…
Based on the graph, explain how centripetal force is affected when the hanging mass changes. Does your graph verify the relationship in the equation r = x^i + y^j = r cos ωt I + r sin ωt^j?
Can you help me to solve this two questions can you teach me step by step how to solve it.
