Dos cargas puntuales, q1 = - 9 µC y q1 = - 25 µC se encuentran respectivamente en X= 0 m y x= 8 m. Encuentre: a) En qué lugar sobre el eje x se debe colocar una tercera carga q3 =4 µC, de 5g de masa, para que esté en equilibrio.

b) Si se coloca luego (con la carga en equilibrio) un alambre infinito uniforme de densidad lineal de carga λ0=4πx10−2 C/m paralelo al eje x en y = -1 m , determine cuál es la densidad superficial de carga que debe tener un disco uniforme de radio R = 0,25 m que pasa por y = 1 m , paralelo al plano yz, que se coloca con su eje paralelo a la línea que pasa por q3, para que se siga manteniendo la carga q3 en equilibrio. Nota desprecie los efectos gravitacionales.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
