3. cherise coloca carros magnéticos idénticos sobre dos rieles. al final de cada riel se encuentra un imán grande que no puede moverse. cherise puede mover los carros un espacio a la izquierda o un espacio a la derecha. ¿cuál de estos movimientos resultará en el mayor aumento de energía potencial?\na mover el carro sobre el riel 1 un espacio a la derecha (→).\nb mover el carro sobre el riel 2 un espacio a la izquierda (←).\nc mover el carro sobre el riel 2 un espacio a la derecha (→).\nd cada uno de estos movimientos resultará en el mismo cambio de energía potencial porque cada uno mueve un carro la misma distancia.
Answer
Explanation:
Step1: Recall magnetic - potential - energy principle
The magnetic potential energy of a magnetic object near a magnet increases as the distance between them decreases (when work is done against the magnetic force).
Step2: Analyze each option
Since at the end of each rail there is a large non - movable magnet, moving a magnetic car towards the magnet will increase the magnetic potential energy. Moving a car on either rail to the side closer to the magnet will result in an increase in potential energy. But we need to find the maximum increase. Moving a car on either rail towards the magnet (i.e., moving a car on Rail 1 to the right or a car on Rail 2 to the right) will bring the car closer to the non - movable magnet at the end of the rail, increasing the magnetic potential energy. Moving a car to the left on Rail 2 moves it away from the magnet at the end of the rail, decreasing potential energy. And just moving the same distance is not the key factor; direction relative to the magnet matters.
Answer:
C. Mover el carro sobre el Riel 2 un espacio a la derecha (→).
