Question

The question: the distance between two parallel plates of capacitor is 'a'. A conductor of thickness b(<a) is inserted between the plates. The variation of effective capacitance between the terminals A and B as a function of the distance (x) of conductor from upper plate is best represented by the graphs​

Answer 1

Answer:

Let the positively charged plate is x = 0 and negatively charged plate is at x = 5d . Two slabs one of the conductor and other of a dielectric of equal thickness d are inserted between the plates as shown in the figure. Potential versus distance graph will look like: ... Thus (B) is represent the best curve.
