The area of each plate of a parallel plate capacitor is $100 \mathrm{cm}^2$ and the distance between the plates is 1 m m . It is filled with mica of dielectric 6. The radius of the equivalent capacity of the sphere will be
Text Solution
Verified by ExpertsThe correct answer is:
B
$C = \frac{\epsilon_0 A K}{d} = 4 \pi \epsilon_0 r$
r = Radius of sphere of equivalent capacity
⇒ ⇒ $r = \frac{AK}{4 \pi d} = \frac{100 \times 10^{-4} \times 6}{1 \times 10^{-3} \times 4 \times 3.14}$ $= \frac{15}{3.14} = 4.77 \, m$
