Question 1:
easyAssertion (A): A changing magnetic flux induces an electric field.
Reason (R): An inductor always tends to keep the flux constant.
Faraday's Law states a changing magnetic flux induces an electric field. Inductors oppose change in flux, but don't keep it constant. Hence, Assertion is true and Reason is false.
Question 2:
easyAssertion (A): Magnetic flux is a vector quantity.
Reason (R): Value of magnetic flux cannot be negative.
Magnetic flux \(\phi = \vec{B} \cdot \vec{A}\) is a scalar quantity (A is false). Also, \(\phi = BA cos\theta\) can be negative when \(cos\theta\) is negative, indicating direction relative to area normal (R is false). Both are false.
