Given below are two statements: one is labelled as Assertion $\displaystyle \mathbf{A}$ and the other is labelled as Reason RAssertion A: A bar magnet dropped through a metallic cylindrical pipe takes more time to come down compared to a non-magnetic bar with same geometry and mass.Reason R: For the magnetic bar, Eddy currents are produced in the metallic pipe which oppose the motion of the magnetic bar.In the light of the above statements, choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
(1)
Both $\displaystyle \mathbf{A}$ and $\displaystyle \mathbf{R}$ are true and $\displaystyle \mathbf{R}$ is the correct explanation of $\displaystyle \mathbf{A}$
