Question: A parallel-plate capacitor is constructed with circular plates of radius 0.051 m. The plates are separated by 0.25 mm, and the space between the plates

A parallel-plate capacitor is constructed with circular plates of radius 0.051 m. The plates are separated by 0.25 mm, and the space between the plates is filled with a dielectric with dielectric constant k. When the charge on the capacitor is 1.8 (C the potential difference between the plates is 1150 V. Find the value of k?
