force on dielectric
one way is energy conservation which gives the ans in the book ( i checked). but why cant i do force on dielectric with battery disconnected = mg

Electric force kya likha hai im unable to understand
force on dielectric with x length in capacitor when battery is disconnected
put x=h
I cant see properly apne kya likha hai but it should be (k-1)Ebv^2/2d
E is epsilon
v is involved when the capacitor in which dielectric is inserted is also connected to a battery
Here the capacitor was charged first , then disconnected from battery and then dielectric was inserted
There are two cases of force on dielectric right ?
There are two cases but the value of force is constant the only diffrence is when cell is connected ut provides the energy to pull the dielectric inside and when the cell is not connected it pulls the dielectric inside using its own energy
Thats why potential energy decreases in this case
the value of force is different in both cases
@Opt inputs?
Once I get home, if I have braincells left
Ok, I don't even understand why the liquid is rising.
What does length mean here? The perimeter or the side of what I'm assuming to be a square?
length is height of plate
width of plate is not given
Is the answer $\frac{\epsilon_{0}.K^{2}V^{2}}{2d^{2}\rho.g}$?

nahh
Lol I should just quit atp.
nah uve been out of touch
That's just excuses my man. I'm weak at phy. ;_;
sure man
(still asked craziest doubts)
Is it?
Battery connected to capacitor
Battery disconnected
Oh right I missed this.
One very obvious way to see my answer was wrong was setting k=1. 🤦♂️
what type of file is this bruh
consider me new 🙂
oh yeah ive done this problem
anyone ???
Let me see
seen?
maybe he's got slow internet
Hua nahi tha😭
