Net force is always zero between capacitor isliye remains unchanged
Right?

Force between plates of a capacitor with dielectric a battery
My teacher told me that the force will increase $k^2$ times, where $k$ is the dielectric constant, but I don't see how. To start with, with no dielectric, the force between the plates is given by $...
Yes, you are correct. The net force between the plates of an isolated capacitor is indeed zero because the forces on the two plates are equal in magnitude and opposite in direction, thus canceling each other out. When a dielectric is inserted, while the force per unit area (electrostatic pressure) between the plates changes, the net force on the system remains unchanged because the system remains in equilibrium.
So, the net force remains zero and does not change due to the insertion of the dielectric.
Given this, none of the provided options (a, b, or d) accurately describes the net force situation. The answer should be that the net force remains unchanged.

I believe it's not though, I am using an extension, which is most of the time correct. Sorry for that man
I didn't meant to offend anyone but sorry
Its alright. Please keep this in mind in the future :) no bot answers unless you have verified them and they are correct.
i did cross checked it
Are itna tension mat le
but whatever man sry
there are actually 3 cases to this
1)dielectric is partiallty filled b/w them and is not touching the plates then it will remain const
2)dielectric is completely filled and its isolated then it would decrease proportional to 1/k
3)dielectric is comepletely filled and its maintained at a fixed pd then it will increase by factor of k
Thanks
