SATHEE: Electrostatics Question 78

Electrostatics Question 78

Question: The area of the plates of a parallel plate condenser is $A$ and the distance between the plates is $10 m m$ . There are two dielectric sheets in it, one of dielectric constant 10 and thickness $6 m m$ and the other of dielectric constant 5 and thickness $4 m m$ . The capacity of the condenser is [MP PMT 1997]

Options:

A) $\frac{12}{35} ε_{0} A$

B) $\frac{2}{3} ε_{0} A$

C) $\frac{5000}{7} ε_{0} A$

D) $1500 ε_{0} A$

Show Answer

Answer:

Correct Answer: C

Solution:

$C = \frac{ε_{0} A}{(\frac{t_{1}}{k_{1}} + \frac{t_{2}}{k_{2}})} = \frac{ε_{0} A}{\frac{6 \times 10^{- 3}}{10} + \frac{4 \times 10^{- 3}}{5}} = \frac{5000}{7} ε_{0} A$
