Answer 1

Answer:

Where is the figure?

Give the proper question.

Answer 2

Answer:

(C) (5/3) (A∈0 / d)

                  Let value of each capacitance be C

                    hence

                   Now C & 2C are in series hence equivalent C' is

                             C' = [(1 / C) + (1 / 2C)]–1

                             C' = (3 / 2C)–1

                             C' = (3/2)C

                   Now C' & C are in parallel hence CTotal = C + (2/3)C

                             ∴CTotal = (5/3)C = (5/3)[(A∈0) / d]
