$(2R-R)2)$ Figure $2$ shows a spherical insulator with uniform charge density $>0$ and a conductor with a surface charge density both with radii of $R.$ A particle with mass $m$ and charge of $q_0>0$ starts at rest at point $A.$ Find the acceleration of the particle at point $A.$ Find the velocity of the particle at point $B.$
