Question

When a dielectric slab of thickness 6 cm is introduced between the plates of parallel plate condenser it is found that the distance between the plates has to he increased by 4 cm to restore to capacity to original value. The dielectric constant of the slab is

  1. 1.5
  2. 2/3
  3. 3
  4. 4

A
1.5
B
3
C
4
D
2/3
Solution
Verified by Toppr

Let initial capacitance be C
C=εoAd A and d are in cm

Final capacitance is same as initial capacitance.
dεoA=d+46εoA+6KεoA
Solving, we get:
K=3
