MHT CET · Physics · Capacitance
The plates of a parallel plate capacitor are separated by a distance 'd' with air as the medium between them. A dielectric slab of dielectric constant 3 is introduced between the plates so as to increase the capacity by \(50 \%\). The thickness of the dielectric slab is
- A \(\frac{d}{2}\)
- B \(\frac{d}{3}\)
- C \(\frac{\mathrm{d}}{5}\)
- D \(\frac{5 d}{6}\)
Answer & Solution
Correct Answer
(A) \(\frac{d}{2}\)
Step-by-step Solution
Detailed explanation
\(C_0 = \frac{\epsilon_0 A}{d}\) \(C = 1.5 C_0 = \frac{\epsilon_0 A}{d - t + \frac{t}{K}}\)
