Tres cargas puntuales se encuentran a lo largo del eje x. La carga positiva q1 = 15,0 mC está en x = 2,00m, la carga positiva q2 = 6,00 mC está en el origen y la
fuerza neta que actúa sobre q3 es cero. ¿Cuál es la coordenada x de q3?

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
