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 paltes of Q so that the entire space is occupied by the dielectric and if U is the energy stored before the insertion of dielectric then stored energy after the dielectric slab is introduced is |
