NASA is currently using ion thrusters to power a spacecraft traveling toward the asteroid Ceres. Its fuel is ionized Xenon atoms. The ions are accelerated through a potential difference out the back of the spacecraft. Each ion has a mass of 2.18E-25kg and a charge of +1.6E-19C. If the ions travel .001m and pass through a potential difference of -1000V, find

(a) the strength of the electric field Blank 1

(b) the change in velocity of the ions Blank 2 .
