PassageII We have two parallel plate capacitors P and Q having same capacitance C_(0). P is connected to a battery of potential difference V and it remains connected to the battery even after the charging is over. Q is also connected to a battery of the same potential difference V but after the charging gets over, it is disconnected from the battery. Answer the following questions: If dielectric slab of dielectric constant 5 is inserted in between the plates of Q so that entire space is occupied by the dielectric. If E is the electric field intensity between the plates before the insertion of dielectric then electric field intensity after the dielectric slab is introduced is

Answer»

E
`E//5`
5E
None of these

Solution :In the GIVEN passage we should known that potential difference between the plates of P remains constant WHEREAS charge stored in Q will REMAIN constant. All ANSWER are to be obtained keeping these THINGS in mind.
