{"problem":"A dielectric sphere of radius \\\\( a \\\\) and absolute permittivity \\\\( \\\\varepsilon \\\\) is moving in a magnetic field `\\(\\vec{B}=-B_{0}\\hat{y}\\)` with constant velocity `\\(\\vec{v}=v\\hat{z}\\)`. Assume that `\\(v\\)` is much smaller than the speed of light. At the instant when the center of the sphere passes through the origin of the coordinates, find the electric field \\\\( \\\\vec{E} \\\\) outside the sphere in terms of \\\\( v \\\\), \\\\( B_0 \\\\), \\\\( a \\\\) and the distance to the center of the sphere \\\\( r \\\\). Leave your answer in vector form, not as a function of angles.\n\nThink step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.","subject":"physics"}
