Solution


Q.

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Magnetic monopoles do not exist.

Reason (R) : Magnetic field lines are continuous and form closed loops.

In the light of the above statements, choose the most appropriate answer from the options given below:          [2025]
1 Both (A) and (R) are correct but (R) is not the correct explanation of (A)  
2 (A) is correct but (R) is not correct  
3 Both (A) and (R) are correct and (R) is the correct explanation of (A)  
4 (A) is not correct but (R) is correct  

Ans.

(3)

The magnet does not exist in form of monopole and magnetic lines never intersect, are continuous and form a closed loop. Line initiates from north pole and end to south pole outside while inside vice versa.

It means both statements are correct and reason is also the correct explanation of assertion.
