True statement for Cathode Ray are (a) Travel in straight line in absence of electrical or magnetic field. (b) Characteristics depend upon the material of electrodes of tube. (c) Characteristics does not depend upon the nature of gas present in cathode ray tube.

Options

  1. Aa, c
  2. Ba, b
  3. Cb, c
  4. Da, b, c

Correct answer

B. a, b

Step-by-step solution

- (a): Travel in a straight line in the absence of electrical or magnetic fields: This statement is true. Cathode rays (electrons) travel in straight lines when no external fields are present. (b): Characteristics depend upon the material of electrodes of the tube: This statement is also true. The characteristics of cathode rays can vary depending on the material of the cathode. - (c): Characteristics do not depend upon the nature of gas present in the cathode ray tube: This statement is not true. The nature of the
