Question

Let f(x) = open parentheses fraction numerator open vertical bar sin invisible function application x rightwards arrow over short leftwards arrow close vertical bar over denominator cos invisible function application x end fraction plus fraction numerator sin invisible function application x over denominator open vertical bar cos invisible function application x close vertical bar end fraction close parentheses
Assertion (A): Fundamental period of f(x) is 2straight pi
Reason (R) : period of sin x and cos x is 2straight pi

  1. If both (A) and (R) are true, and (R) is the correct explanation of (A)    
  2. If both (A) and (R) are true but (R) is not the correct explanation of (A)    
  3. If (A) is true but (R) is false.    
  4. If (A) is false but (R) is true.    

The correct answer is: If (A) is false but (R) is true.

    As shown in the figure, P and Q are two coaxial conducting loops separated by some distance. When the switch S is closed, a clockwise current I subscript P end subscript flows in P (as seen by E) and an induced current I subscript Q subscript 1 end subscript end subscript flows in Q. The switch remains closed for a long time. When S is opened, a current I subscript Q subscript 2 end subscript end subscript flows in Q. Then the directions of I subscript Q subscript 1 end subscript end subscript and I subscript Q subscript 2 end subscript end subscript (as seen by E) are
