Electrostatic Potential and Capacitance - Result Question 29
31. Two thin dielectric slabs of dielectric constants $K_1$ and $K_2(K_1<K_2)$ are inserted between plates of a parallel plate capacitor, as shown in the
figure. The variation of electric field ’ $E$ ’ between the plates with distance ’ $d$ ’ as measured from plate $P$ is correctly shown by : [2014]
(a)
(b)
(c)
(d)
Show Answer
Answer:
Correct Answer: 31. (c)
Solution:
- (c) Electric field, $E \propto \frac{1}{K}$
As $K_1<K_2$ so $E_1>E_2$
Hence graph (c) correctly dipicts the variation of electric field $E$ with distance d.
