MHT CET 2025 Physics question
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
Answer: (A)
Solution
Initially . With a slab of thickness and dielectric constant the capacitance is . A 50% increase means , so
