MCQ
Which one of the following properties is not found in cathode rays?
  • A
    Cathode rays can produce $x-$rays
  • B
    The properties of cathode rays differ from the properties of $x-$rays
  • C
    The cathode rays possess too much kinetic energy
  • ✓
    Cathode rays are not deflected by electric and magnetic field
✓

Answer

Correct option: D.
Cathode rays are not deflected by electric and magnetic field
Properties of cathode rays:
They are produced by the negative electrode, or cathode, in an evacuated tube, and travel towards the anode.
They travel in straight lines and cast sharp shadows.
They have energy and can do work.
They are deflected by electric and magnetic fields and have a negative charge.
