Problema 1 Dos alambres paralelos largos A y B están fijos a una distancia de 8 cm entre sí, en el aire, y conducen comentes de 5 A y 3 A, respectivamente, en direcciones opuestas, (a) Determine la densidad de flujo neta en un punto intermedio entre los alambres, (b) ¿Cuál es la fuerza
magnética por unidad de longitud sobre un tercer alambre colocado en el punto medio entre A y B, que conduce una corriente de 1.5 A en la misma dirección que A?

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
