Accepted Answer

As q = CV
Hence slope of graph will give capacitance. Slope will be more in parallel combination.
Hence capacitance in parallel should be 50 $\mu $F and in series combination must be 8 $\mu $F.
Only in option 40 $\mu $f and 10 $\mu $F.
C
parallel
= 40 + 10 = 50 $\mu $F
C
series
= ${{40 	imes 10} \over {40 + 10}} = 8\mu F$

Answer

40 $\mu $F and 10 $\mu $F

Answer

60 $\mu $F and 40 $\mu $F

Answer

20 $\mu $F and 30 $\mu $F

Answer

50 $\mu $F and 30 $\mu $F
