# Rolling charge

A homogeneous ball with mass $$m=1 ~\mbox{g}$$ and total charge $$q=10^{-3}~\mbox{C}$$ (uniformly distributed) is placed on a horizontal xy plane. The ball starts rolling without slipping under the influence of a uniform electrostatic field $$\vec{E}=(E,0,0)$$ with $$E=1~ \mbox{V/m}.$$ Find the acceleration in meters per second squared of the center of mass of the ball.
