A parallel plate capacitor having capacitance C Farad is connected with a bettery of emf V volts. Keeping the capacitor connected with the bettery, a dieletric slab of dielectric consutant K is inserted between the plates. The dimensions of the slab are such that it fills the space between the capacitor plates, consider the following sttements (i) Potential difference between the capacitor plated remains the same (ii) The capacitance increases by a factor K (iii)The energy stored increases by a factor K Then the correct statements are |

Answer» (i),(ii) `therefore` V=constant `C=(epsi_(0)KA)/(d)` `C prop K` `U=(1)/(2)CV^(2)` `U prop C` `U prop K` |
