Given below are two statements:
Statement (I) : When currents vary with time, Newton's third law is valid only if momentum carried by the electromagnetic field is taken into account.
Statement (II) : Ampere's circuital law does not depend on Biot-Savart's law.
In the light of the above statements, choose the correct answer from the options given below:
Statement (I) : When currents vary with time, Newton's third law is valid only if momentum carried by the electromagnetic field is taken into account.
Statement (II) : Ampere's circuital law does not depend on Biot-Savart's law.
In the light of the above statements, choose the correct answer from the options given below:
- (A)Both Statement I and Statement II are false.
- (B)Statement I is true but Statement II is false.✓ Correct
- (C)Statement I is false but Statement II is true.
- (D)Both Statement I and Statement II are true.
Answer: (B)
Solution
Statement I is true — with time-varying currents momentum conservation (Newton's third law) holds only when the field's momentum is included. Statement II is false — Ampere's law is consistent with, not independent of, Biot–Savart. So I true, II false. Option (2).
