Explanation The initial energy of the electron before the firing process is zero. According to the principle of conservation of energy, the total energy of each electron after firing process also must be zero. Write the expression for the total energy of the electron after the firing process. E = 0 (I) Here, E is the total energy of each electron after the firing process. Write the expression for E . E = K f + U f Here, K f is the kinetic energy of the electron after the firing process and U f is the potential energy of the electron after the firing process. Put the above equation in equation (I). K f + U f = 0 (II) Write the equation for K f . K f = 1 2 m u 2 Here, m is the mass of the electron and u is the speed of the electron. Write the equation for the potential energy of the electron. U f = − e V Here, − e is the charge of the electron and V is the potential difference through which the electron is accelerated. Put the above two equations in equation (II) and rewrite it for u . 1 2 m u 2 + ( − e V ) = 0 1 2 m u 2 − e V = 0 u 2 = 2 e V m u = 2 e V m (III) Write the equation for the time of flight of the electron. Δ t = Δ x u (IV) Here, Δ t is the time of flight of the electron and Δ x is the distance travelled by the electron in the tube
