Question

.

A very large (i.e., assume infinite) flat slab of nonconducting material has thickness d and a uniform positive volume charge density + rho E. The slab is aligned so that one of its surfaces lies on the line y = x. Determine magnitude and direction (relative to the slab's surface) of the electric field outside the slab. Write it using x and y coordinates. At time t = 0, a pointlike particle (mass m, charge +q) is located at position r rightarrow = y0y^, and has the velocity v rightarrow v0x^. Show that the particle will collide with the slab if v0 . Ignore gravity.
