  1. Jan 26, 2008 #1
    1. The problem statement, all variables and given/known data
    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.


    2. Relevant equations

    3. 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.

    Mindscrape is trying to help you. You may want to re-read this sticky towards the top of this subforum page. It will explain that help is only given to those who show their work.
