Capacitor question

2022 · Shift 1 · Q45

JEE AdvancedPhysicsCapacitorMultiple correct+4 / −2
A medium having dielectric constant K>1K\gt 1K>1 fills the space between the plates of a parallel plate capacitor. The plates have large area, and the distance between them is ddd. The capacitor is connected to a battery of voltage VVV, as shown in Figure (a). Now, both the plates are moved by a distance of d2\frac{d}{2}2d​ from their original positions, as shown in Figure (b). JEE Advanced 2022 Paper 1 Online Physics - Capacitor Question 6 English In the process of going from the configuration depicted in Figure (a) to that in Figure (b), which of the following statement(s) is(are) correct?
  1. A
    The electric field inside the dielectric material is reduced by a factor of 2K2 K2K.
  2. B
    The capacitance is decreased by a factor of 1K+1\frac{1}{K+1}K+11​.
  3. C
    The voltage between the capacitor plates is increased by a factor of (K+1)(K+1)(K+1).
  4. D
    The work done in the process DOES NOT depend on the presence of the dielectric material.
