A large vessel is filled with a liquid. Two vertical plates touch the surface of the liquid. The dimensions of the plate are a and b, the distance between them is d. The plates have been charged by applying a voltage V and then disconnected form the voltage source. To what height will the liquid rise. (the density of liq is k) and what happens to height if voltage remains connected?

Dear Student,

force on the liquid=CV22Aε0=CV22abε0,A=abC=ε0abdF=ε0abVd22abε0=abε0V22d2let the rise be xabε0V22d2=daxkgbε0V22d3kg=x is the rise Regards
