A electric field of $1.5 \times 10^{4} N C^{- 1}$ exists between two parallel plates of length 2 cm. An electron enters the region between the plates at right angles to the field with a kinetic energy of $E_{k} = 2000 e V .$ The deflection that the electron experiences at the deflecting plates is:

Q. An electron is projected with an initial speed

v_{0} = 1.60 \times 10^{6} m s^{- 1}

into the uniform field between the parallel plates as shown in figure. Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates. Mass of electron is
