11. In a cathode-ray tube, electrons are accelerated from the cathode towards the anode by an accelerating voltage Va. After passing through the anode, the electrons are deflected by the two oppositely-charged parallel plates. Cathode -jif deflection If the accelerating voltage Va is decreased, will the deflection increase, decrease, or remain the same? Using principles of physics, explain your answer. [K 4 marks]
