Answer
$a=9.5\times 10^8\frac{m}{s^2}$
Work Step by Step
We will use the following equation to solve this question:
$F_B=ma$
First, we need to rearrange this equation to make $a$ the subject of the equation:
$a=\frac{F_B}{m}$
We plug in the known values to obtain:
$a=\frac{6.24\times 10^{-18}}{6.6\times 10^{-27}}$
$a=9.5\times 10^8\frac{m}{s^2}$
