The distance between the plates of a charged plate capacitor disconnected from the batteryis 5cm and the intensity of the field in it is `E=300V//cm`. An uncharged metal bar `1cm` thick is introduced into the capacitor parallel to its planes. The potential difference between the plates now is :

The distance between the parallel plates of a charged condenser is d= 5cm and the intensity of the field e = 300V//cm . A slab of dielectric constant k= 5 and 1 cm wide is inserted parallel to the plates. Determine the potential difference between the plates before and after the slab is inserted. If the slab is replaced by a metal plates so that the final potential difference remains unchanged, what be the thickness ofthe plate?

The distance between the plates of a parallel plate capacitor is "4cm" .An electric field of 2times10^(4) V/m is established between the plates.It is then disconnected from the battery and an uncharged metal plate of thickness "1cm" is inserted into the capacitor parallel to it's plates.The potential difference between the plates of capacitor after the introduction of the metal plate is k times10^(2) V .The value of ' "k" s

The distance between the plates of a charged parallel plate copacitor is 5cm and electric field inside the plates is 200V cm^(-1) . An uncharged metal bar of width 2 cm is fully immersed into the capacitor. The length of the metal bar is same as that of plate of capacitor. The voltage across capacitor after the immersion of the bar is-

The' distance between the plates of a parallel plate capacitor is d . A metal plate of thickness d//2 is placed between the plates. What will e its effect on the capacitance.

The' distance between the plates of a parallel plate capacitor is d . A metal plate of thickness d//2 is placed between the plates. What will e its effect on the capacitance.

The separation between the plates of a parallel plate capacitor is t, and the intervening space is filled with glass, of dielectric constant 6. Now, the separation between the plates is increased by t. How would the charge on the capacitor and the potential difference between its plates charge, if The battery is disconnected before increasing the separation between the plates?
