A parallel plate capacitor with plate area A and plate separation $\displaystyle \mathrm{d}=2 \mathrm{~m}$ has a capacitance of $\displaystyle 4 \mu F$. The new capacitance of the system if half of the space between them is filled with a dielectric material of dielectric constant $\displaystyle \mathrm{K}=3$ (as shown in figure) will be :
Official answer
(3)
$\displaystyle 6 \mu F$
