Un cuerpo con un peso de magnitud igual a 200 N cuelga sobre dos cuerdas que forman un ángulo de 140° entre ellas. Determina la magnitud de la fuerza que ejerce cada cuerda sobre el cuerpo.

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
