AI Thread Summary
In a discussion about a parallel plate capacitor with one plate dipped in water, the initial charge on the lower plate is Q, while the upper plate has a charge of 2Q. The dielectric constant of water is denoted as K, and the question revolves around determining the final charge on the lower plate after dipping it in water. One participant claims the final charge is 3Q/2 and seeks validation of this answer. However, others emphasize the importance of showing work for accurate feedback, suggesting that help is contingent upon demonstrating the reasoning behind the solution. The conversation highlights the challenges of seeking assistance without providing detailed calculations.

Homework Statement


A parallel plate capacitor with the separation between the plates as 'd' has its lower plate dipped in water. Before dipping, the lower plate has charge Q, while the upper plate has charge 2Q. Let K be the dielectric constant of water. What will be the final charge on the lower surface of the plate dipped in water.


Homework Equations



The Attempt at a Solution


I am not showing the equations and attempt to my solution.
The answer I got is 3Q/2, can anyone comment on if my answer is correct.

its so much time taking to show the work... if u can just tell yes or no.. its sufficient for me.. thanks in advance..
 
Mindscrape is trying to help you. You may want to re-read this https://www.physicsforums.com/showthread.php?t=94379 towards the top of this subforum page. It will explain that help is only given to those who show their work.
 
i m just forced to post my questions in this homework forum because of the warnings i get.. these questions are not homewrk questions.. i m just trying to understand the subject myself.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
