JEE MAIN - Physics (2024 - 6th April Evening Shift - No. 11)
Match List I with List II:
| LIST I (Y vs X) |
LIST II (Shape of Graph) |
||
|---|---|---|---|
| A. | Y-magnetic susceptibility X = magnetising field |
I. | _6th_April_Evening_Shift_en_11_1.png) |
| B. | Y = magnetic field X = distance from centre of a current carrying wire for x < a (where a = radius of wire) |
II. | _6th_April_Evening_Shift_en_11_2.png) |
| C. | Y = magnetic field $$\mathrm{X}=$$ distance from centre of a current carrying wire for $$x>\mathrm{a}$$ (where $$\mathrm{a}=$$ radius of wire) |
III. | _6th_April_Evening_Shift_en_11_3.png) |
| D. | Y = magnetic field inside solenoid X = distance from centre |
IV. | _6th_April_Evening_Shift_en_11_4.png) |
Choose the correct answer from the options given below :
(A)-(III), (B)-(IV), (C)- (I), (D)-(II)
(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
(A)-(I), (B)-(III), (C)-(II), (D)-(IV)
Explanation
In para and dia materials, susceptibility is independent of magnetic field.
Inside a current carrying wire, $$B \propto X$$
Outside a current carrying wire, $$B \propto \frac{1}{x}$$
Inside a solenoid, B is constant upto ends.
