[JEE Main 10-4-2019 Morning]
A) \[50\mu F\text{ }and\text{ }30\mu F\]
B) \[20\mu F\text{ }and\text{ }30\mu F\]
C) \[60\mu F\text{ }and\text{ }40\mu F\]
D) \[40\mu F\text{ }and\text{ }10\mu F\]
Correct Answer: D
Solution :
As q = CV Hence slope of graph will give capacitance. Slope will be more in parallel combination. Hence capacitance in parallel should be \[50\mu F\]& in series combination must be \[8\mu F\]. Only in option \[40\mu F\text{ }\And \text{ }10\mu F\] \[{{C}_{parallel}}=40+10=50\mu F\] \[{{C}_{series}}=\frac{40\times 10}{40+10}=8\mu F\]
