Part A

A point charge $q_1=15\mathrm{.}00C$ is held fxed in space. From a horizontal distance of $8\mathrm{.}00cm,$ a small sphere with mass $4\mathrm{.}00{10}^{-3}kg$ and charge $q_2=+2\mathrm{.}00C$ is fired toward the fixed charge with an initial speed of $44\mathrm{.}0\frac{m}{s}.$ Grarity can be neglected.

What is the acceleration of the sphere at the instant when its speed is $28\mathrm{.}0\frac{m}{s}?$

Express your answer with the appropriate units.

$a=5\mathrm{.}27*{10}^{-8}$
