Identical dielectric slabs are inserted into two identical capacitors `A` and `B`. These capacitors and a battery are connected as shown in figure. Now the slab of capacitor `B` is pulled out with battery remaining connected

The answer to each of the following questions is a single-digit integer ranging from 0 to 9. Darken the correct digit. Two identical air capacitors of capacitance C are connected to a battery of EMF V and initially switch is closed for a long time. After the switch is opened, identical dielectric slabs are inserted in between the plates of both the capacitors and it is found that energy stored in capacitor B becomes nine times of the energy stored in capacitor A. What is the dielectric constant of the slab?

When a dielectric slab is inserted between the plates of one of the two identical capacitors shown in the figure then match the following:

Two identical capacitors with identical dielectric slabs in between them are connected in series as shown in. Now, the slab of one capacitor is pulled out slowly with the help of an external force F at steady state as shown. Mark the correct statement(s). .

An air core parallel plate capacitor has capacitance C. It is completely filled with a dielectric slab having dielectric constant 2 K. The capacitor is now connected to a battery of emf V. It was planned to replace the dielectric slab of the capacitor while it remains connected to the battery. Another dielectric slab (which fits exactly between the plates) is inserted slowly so as to push out the earlier slab. The new slab has a dielectric constant K [see Figure (a) to (c)] (a) By energy considerations calculate the mechanical work that must be done against the electric forces in order to complete the process. (b) Looking at the expression of mechanical work obtained in (a), tell what was the direction of force applied by the external agent - from left to right (as indicated by F_(1) in Figure) or from right to left (as indicated by F_(2) ). (c) Which dielectric slab experienced higher force of attraction from the capacitor plates during the process ?
