Between two horizontal parallel plates, uniform electric field `E` directed vertically downward. A charged particle `(q,m)` remains in equilibrium in vaccum between the plates. Find shortage/excess of electrons in the charged particle .

An electron is projected with an initial speed v_(0)=1.60xx10^(6)ms^(-1) into the uniform field between the parallel plates as shown in fig. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. the electrons enters the field at a point midway between the plates. Mass of electron is 9.1xx10^(-31)kg . The vertical displacement traveled by the proton as it exits the region between the plated is (mass pf proton is 1.67xx10^(-27)kg ).

A parallel plate capacitor has a uniform electric field E(V/m) in the space between the plates. If the distance between the plates is d(m) and area of each plate Is A(m^2) the energy (joule) stored in the capacitor is
