JEE Main 2022 Physics question
A parallel plate capacitor is formed by two plates each of area separated by 1 mm. A material of dielectric strength is filled between the plates. If the maximum charge that can be stored on the capacitor without causing any dielectric breakdown is C, the value of dielectric constant of the material is : [Use ]
Answer: (4)
Solution
The field inside the dielectric is , and it equals the dielectric strength at the limit: . With $A =
