Electrostatics Question 805
Question: A parallel plate air capacitor has a capacitance of $ 100\mu F. $ The plates are at a distance d apart. If a slab of thickness t(t<d) and dielectric constant 5 is introduced between the parallel plates, then the capacitance will be
Options:
A) $ 50\mu F $
B) $ 100\mu F $
C) $ 200\mu F $
D) $ 500\mu F $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Capacitance will increase but not 5 times (Because dielectric is not filled completely). Hence, new capacitance maybe $ 200\mu F $ ,
