**A paper is placed between two plates of copper , area 100 cm^2. The thickness of the paper 0.005cm and its dielectric constant is 2.5 . If the paper can bear an electric field of 5 x 10^5 V/cm then calculate the maximum voltage upto which the capacitor can be charged.How much charge will be stored on the capacitor ?**

**My attempt -> A=100cm^2**

K=2.5

5x10^5=9x10^9 x q / r

K=2.5

5x10^5=9x10^9 x q / r
