Задача id12430

The centers of two non-metallic fixed spheres of radius R=10 cm, over the surface of which the same positive charge q1=2 • 10-7 C is uniformly distributed, are located at a distance l=24 cm from each other. Small holes are made in the spheres along the center line. A negatively charged particle with a charge q2=1•10-7 C moves along this line, having a speed close to zero at the midpoint between the spheres. What is the maximum distance it will move from this point?
