If the slab is brought inside the parallel plate capacitor with a speed v . Then the variation of d c d t with respect to v is d c d t = R a t e c h a n g e o f c a p a c i t a n c e -
Correct answer
1
Step-by-step solution
C e q = C 1 + C 2 = ε 0 b x K d + ε 0 l – x b d = ε 0 b d l b + x K - 1 ∴ d c d t = ε 0 b d K - 1 d x d t = ε 0 b d K - 1 V
