Question

Assertion: An aircraft flies along the meridian, the potential at the ends of its wings will be the same. 

Reason: Whenever there is a change in the magnetic flux, and emf is induced.

(a) If both assertion and reason are true and the reason in the correct explanation of the assertion.

(b) If both assertion and reason are true but the reason is not correct explanation of the assertion.

(c) If assertion is true but reason is false.

(d) If the assertion and reason both are false.

(e) If assertion is false but reason is true.

Answer 1

(e) If assertion is false but reason is true.

As the aircraft flies magnetic flux change through its wings due to the vertical component of the Earth’s magnetic field. Due to this, induced emf is produced across the wings of the aircraft. Therefore, the wings of the aircraft will not be at the same potential.
