Interpretation:
The direction of cathode-ray inside a cathode-ray tube needs to be explained.
Concept introduction:
Electricity travels from cathode to anode.
Answer to Problem 50A
Cathode-ray travels from cathode to anode of a cathode-ray tube.
Explanation of Solution
Cathode-ray consists of electrons which are negatively charged particles. Anode end in cathode-ray tube is connected to the positive terminal of a battery. Since, electrons are negatively charged they get attracted towards the positive terminal, i.e., anode. Due to this, cathode-ray originates from cathode and travels to anode.
Cathode-ray originates from cathode and end to anode.
