An electron is projected with an initial velocity of 10^(7)ms^(-1) into an electric field between two parallel plates 1 cm apart. The electron enters the field at a point midway between the plates. If the electron just misses the positivity charged plate as it emerges from the field, find the magnnitude of the electric density between the plates. (Length of each plate is 2 cm, mass of electron= 9xx10^(-31) kg and charge of electron =1.6xx10^(-19) C)
