MCQ
A parallel plate capacitor with air as medium between the plates has a capacitance of $10\ \mu F.$ The area of capacitor is divided into two equal halves and filled with two media as shown in the figure having dielectric constant $k_1=2$ and $k_2=4$. The capacitance of the system will now be


- A$10\ \mu F.$
- B$20\ \mu F.$
- ✓$30\ \mu F.$
- D$40\ \mu F.$
