Una barra conductora de L = 0,9 m se mueve sin fricción sobre dos rieles conductores horizontales, Unos extremos de los rieles se conectan a una batería de 15 V y un interruptor. La barra se mueve en una región donde existe un campo magnético uniforme
B = −1,5 ˆz T. La barra tiene una masa de 0,5 kg y una resistencia de 8 Ω.
a) Encuentre la aceleración de la barra, en t = 0 s, justo cuando se cierra el interruptor.
b) Encuentre la aceleración de la barra cuando se mueve hacia la derecha con rapidez 2 m/s.
