Solution

Q.
Match the Column – I with Column – II: [2023]

Choose the correct answer from the options given below:

1 A – I; B – III; C – IV; D – II

2 A – III; B – IV; C – I; D – II

3 A – II; B – I; C – IV; D – III

4 A – III; B – I; C – IV; D – II

Ans.
(4)

$A \to B_{0} = \frac{μ_{0}}{4 π} \frac{i}{r} ⊙ + \frac{μ_{0} i}{2 r} \otimes + \frac{μ_{0}}{4 π} \frac{i}{r} ⊙$

$= \frac{μ_{0}}{2 π} \frac{i}{r} ⊙ + \frac{μ_{0} i}{2 r} \otimes$

$B_{0} = \frac{μ_{0} i}{2 π r} (π - 1) \otimes$

$B \to B_{0} = \frac{μ_{0}}{4 π} \frac{i}{r} ⊙ + \frac{μ_{0}}{4 π} \frac{i}{r} π ⊙ + \frac{μ_{0}}{4 π} \frac{i}{r} π ⊙$

$= (\frac{2 μ_{0}}{4 π} \frac{i}{r} + \frac{μ_{0}}{4 π} \frac{i}{r} π) ⊙$

$B_{0} = \frac{μ_{0} i}{4 π r} (2 + π) ⊙$

$C \to B_{0} = \frac{μ_{0}}{4 π} \frac{i}{r} \otimes + \frac{μ_{0}}{4 π} \frac{i}{r} π \otimes + 0$

$B_{0} = \frac{μ_{0}}{4 π} \frac{i}{r} (1 + π) \otimes$

$D \to B_{0} = \frac{μ_{0}}{4 π} \frac{i}{r} π = \frac{μ_{0}}{4 π} \frac{i}{r} ⊙$

$A - III; B - I; C - IV; D - II$
