A capacitor is made with a polymeric dielectric having a relative permittivity εr of 2.26 and a dielectric breakdown strength of 50 kV/cm. The permittivity of free space is 8.85 pF/m. If the rectangular plates of 20 cm and a length of 40 cm, then the maximum electric charge in the capacitor is
- A. 2 µC
- B. 4 µC
- C. 8 µC
- D. 10 µC
