Magnetism and Matter

154011 A magnetic dipole is under the influence of two orthogonal magnetic field, $B_{1}=0.5 \times 10^{-3} \mathrm{~T}$ and $B_{2}=0.866 \times 10^{-3} \mathrm{~T}$. If the dipole comes to stable equilibrium at an angle $\theta$ with respect to $B_{2}$ field, then the value of $\theta$ is

1 $45^{\circ}$
2 $30^{\circ}$
3 $60^{\circ}$
4 $90^{\circ}$

154012 The distance between $\mathrm{H}^{+}$and $\mathrm{C} T$ ions in $\mathrm{HCl}$ molecules is $1.28 \AA$. The potential due to this dipole at a distance of $12 \AA$ on the axis on dipole is

1 $0.13 \mathrm{~V}$
2 $1.3 \mathrm{~V}$
3 $13 \mathrm{~V}$
4 $130 \mathrm{~V}$

154014 Assertion : The poles of magnet cannot be separated by breaking into two pieces.
Reason : The magnetic moment will be reduced to half when a magnet is broken into two equal pieces.

1 If both Assertion and Reason are correct and reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
3 If Assertion is correct but Reason is incorrect
4 If both the Assertion and Reason are incorrect
Magnetism and Matter

154016 The force between two magnetic poles is $F$. If the distance between the poles and pole strengths of each pole are doubled, then the force experienced is:

1 $2 \mathrm{~F}$
2 $\frac{F}{2}$
3 $\frac{F}{4}$
4 F
5 $4 \mathrm{~F}$
