, . Now, both the plates are moved by a distance d/2 of from their original positions, as shown in Figure to that in Figure The electric field inside the dielectric material is reduced by a factor of 2K.

, . In the process of going from the configuration depicted in Figure , which of the following statement(s) is(are) correct? The capacitance is decreased by a factor of

and The voltage between the capacitor plates is increased by a factor of (K+l).

. ONE OR MORE THAN ONE of these four option(s) is(are) correct answer(s). • For each question, choose the option(s) corresponding to (all) the correct answer(s). • Answer to each question will be evaluated according to the following marking scheme: Full Marks : +4 ONLY if (all) the correct option(s) is(are) chosen; Partial Marks : +3 If all the four options are correct but ONLY three options are chosen; Partial Marks : +2 If three or more options are correct but ONLY two options are chosen, both of which are correct; Partial Marks : +1 If two or more options are correct but ONLY one option is chosen and it is a correct option; Zero Marks : 0 If none of the options is chosen (i.e. the question is unanswered); Negative Marks : -2 In all other cases. A medium having dielectric constant K > 1 fills the space between the plates of a parallel plate capacitor. The plates have large area, and the distance between them is d. The capacitor is connected to a battery of voltage V, as shown in Figure The work done in the process DOES NOT depend on the presence of the dielectric material.
