Options

  1. Aaccelerate the electrons
  2. Bdecrease KE of electrons
  3. Crepel the electrons
  4. Ddecelerate the electrons

Correct answer

C. repel the electrons

Step-by-step solution

In an electron gun, the control grid is given a negative potential relative to cathode in order to repel the electrons so that a converging beam of electrons emerges from gun.
