Answer:
[tex]Q=2.0\times10^{-6}C[/tex]
Explanation:
The equation of charge on the capacitor given its capacitance and a voltage applied to it is Q=CV.
Our capacitance is expressed in microfarads, where micro stands for [tex]\times10^{-6}[/tex], so in S.I. we sill have:
[tex]Q=CV=(0.4\times10^{-6}F)(5V)=0.000002C=2.0\times10^{-6}C[/tex]
Where the results has been expresed with two significant figures.
