In the discharge tube positive rays move in which direction?
Correct answer: B. Towards cathode
- A. Towards anode
- B. Towards cathode
- C. Move randomly
- D. Move towards vacuum in the tube
Explanation
In discharge tube cathode rays (a beam of negative particles) and canal rays (positive rays) moves opposite to each other. They will experience a magnetic force in the same direction, if a normal magnetic field is switched on.Positive charges move towards cathode whereas negative charges move towards the anode.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
