We obtain an exact solution of the space charge problem for a uniformly charged ball moving in an exterior constant homogeneous electric field. The results obtained can be used as tests in the numerical simulation of the effect of a space charge of actual beams and for estimating the accuracy of the numerical methods used in the solution of the space charge problem.
Keywords: space charge problem, motion of a spherically symmetric beam (ball), homogeneous electric field, Newton's second law, Cauchy problem, Gauss's theorem.
