Q. A $10\, V$ power source charges a $5 \,\mu F$ capacitor with air as its dielectric. The power source is removed and the air gap is carefully replaced with a material of dielectric constant $K=5$. What is the final charge on the capacitor ? (in $\mu F$ )

Electrostatic Potential and Capacitance

Solution:

$q'=q=C V=50 \,\mu F$
