Dos cargas positivas se repelen con una fuerza de 3N. Si la primera tiene una magnitud de 6x10 a la -4 C y la otra es de 5x10 a la -4 C. ¿Cuál debe ser la distancia entre las cargas?¿Qué sucederá con la distancia si la fuerza se triplica? Elabora tu figura.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
