Given below are two statements: Assertion (A): An electron moving with a constant velocity in a straight line does not produce an electromagnetic wave. Reason (R): A charge moving with a constant velocity produces both an electric field and a magnetic field in the surrounding space. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A)
  3. CAssertion (A) is true and Reason (R) is false
  4. DAssertion (A) is false and Reason (R) is true

Correct answer

B. Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A)

Step-by-step solution

Assertion (A) is true because an electromagnetic wave is produced only by an accelerating or oscillating charge. An electron moving with a constant velocity has zero acceleration and thus cannot radiate electromagnetic waves. Reason (R) is also true because a moving charge constitutes a current, which produces a magnetic field, while its intrinsic charge produces an electric field. However, Reason (R) does not explain Assertion (A). The correct explanation for the Assertion is that the generation of electromagnetic
