359216 A parallel plate capacitor is formed by two plates each of area \(30\pi c{m^2}\) separated by 1 \(mm\). A material of dielectric strength \(3.6 \times {10^7}\,V{m^{ - 1}}\) is filled between the plates. If the maximum charge that can be stored on the capacitor without causing any dielectric breakdown is \(7 \times {10^{ - 6}}C\), the value of dielectric constant of the material is :

359217 The potential energy of a charged parallel plate capacitor is \(U_{0}\). If a slab of dielectric constant \(K\) is inserted between the plates, then the new potential energy will be

359218 Assertion :
When a dielectric medium is filled between the plates of a condenser, its capacitance increases.
Reason :
The dielectric medium reduces the potential difference between the plates of the condenser.

359219 A slab of copper of thickness \({\dfrac{d}{2}}\) is introduced between the plates of a parallel plate capacitor where \({d}\) is the seperation between its two plates. If the capacitance of the capacitor without copper slab is \({C}\) and with copper slab is \({C^{\prime}}\), then \({\dfrac{C^{\prime}}{C}}\) is
