Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion 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
A is true but R is false
Both A and R are true but R is NOT the correct explanation of A
A is false but R is true
Both A and R are true and R is the correct explanation of A
Answers (1)
Due to Eddy current in the metallic pice which opposes the motion of magnetic bar. So, it takes more time to comes down compared to non-magnetic bar.
