C=Akepslan not/d
If 1pf=k/d
So relation,
2pf=4x/2d so it can com 2pf.
Bhaiya dekho salon ne dala nahi tha explanation hum likh rahe hain.
Before C =1pF
After when d is doubled and dilectric is inserted
C=2pF
So x-
Since C=(ε0.A/d)k after intertion of dielectric
2=(ε0.A/2d)k (given)
2=(C/2)k
2=k/2. (Given)
K=4
