A spherical insulator of radius R is placed at distance of 10R from a spherical conductor of radius R/2 (see Fig). The charge density of the insulator is -ρ and the conductor is σ. The charges are uniformly distributed over the volume of the insulator and the surface of the conductor. A particle with mass of m and positive charge of Q is placed at rest at an equal distance to the centers of both spheres. Find out in which direction the particle moves and its final velocity when hits one of the spheres. . Use: R = 2.0 cm, -ρ = - 1.0 μC/m3, σ- 60.0 nC/m2, Q = 8.85 μC and m = 0.3 ng.
