A parallel plate capacitor of area `100 cm^(2)` and plate separation 8.85 mm is charged to a potential difference of 100 V when air is used between the plates. The capacitor is now isolated and air is replaced by glass `(epsi_(r) - 5)`, then:A. The original capacity will be 10 pFB. The new capacity will be 50 pFC. The new potential difference is 200 VD. The new energy stored is `mu J`
