Q. Cathode rays and canal rays produced in a certain discharge tube are deflected in the same direction if
A) A magnetic field is applied normally
B) An electric field is applied normally
C) An electric field is applied tangentially
D) A magnetic field is applied tangentially
Explanation
(a) In discharge tube cathode rays (a beam of nregative particles) and canal rays (positive rays) move opposite to each other. They will experience a magnetic force in the same direction, if a normal magnetic field is applied
