JEE Main 24 June 2022 Shift 1 Solved Paper

A parallel plate capacitor is formed by two plates each of area 30πcm2 separated by 1‌mm. A material of dielectric strength 3.6×107Vm−1 is filled between the plates. If the maximum charge that can be stored on the capacitor without causing any dielectric breakdown is 7×10−6C, the value of dielectric constant of the material is :
