Question : 5 of 54

Marks: +1, -0

Following operations can be performed on a parallel plate capacitor
X → Connect the capacitor to a battery of emf ε
Y → Disconnect the battery
Z → Reconnect the battery with polarity reversed
W → Insert a dielectric slab in the capacitor

In XYZ (Perform X, then Y and then Z), the stored electrical energy remains unchanged and thermal energydeveloped is 5 times the stored electrical energy
The electric field inside capacitor is greater after the action XWY than that after the action XYW
The charge on the capacitor is greater after the action WXY than that after the action XYW
The charge on the capacitor after the action XW is same as that after WX
