Assertion : An electric field is preferred in comparison to magnetic field for detecting the electron beam in a television picture tube. Reason : Electric field requires low voltage.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

If electric field is used for detecting the electron beam, then very high voltage will have to be applied or very long tube will have to be taken.
