Question

What will happen if in a HOT CATHODE RAY TUBE the

i) voltage or potential difference of the Low Tension battery is increased

ii) voltage or potential difference of the High Tension battery is increased?

• A. i) electrons are emitted at a slower rate and ii) electrons are accelerated with a greater velocity towards the anode
• B. i) electrons are emitted at a greater rate and ii) electrons are accelerated with a smaller velocity towards the anode
• C. i) electrons are emitted at a lower rate and ii) electrons are accelerated with a smaller velocity towards the anode
• D. i) protons are emitted at a lower rate and ii) protons are accelerated with a greater velocity towards the anode
• E. i) electrons are emitted at a greater rate and ii) electrons are accelerated with a greater velocity towards the anode

Answer 1

The correct option is E

i) electrons are emitted at a greater rate and ii) electrons are accelerated with a greater velocity towards the anode
