MCQ
A magnetic needle is kept in a non-uniform magnetic field. It experiences
  • A force and a torque
  • B
    A force but not a torque
  • C
    A torque but not a force
  • D
    Neither a torque nor a force

Answer

Correct option: A.
A force and a torque
a
(a) A magnetic needle is a magnetic dipole.

In a non uniform Magnetic field Force on each of the poles will be different in both magnitude and direction.

Due to difference in Magnitude the dipole experiences a Force,

Due to difference in Direction the dipole experiences a Torque.

The figure shows the intensity-wavelength relations of $X -$rays coming from two different Coolidge tubes. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is $V_A$ and the atomic number of the target material is $Z_A$. These quantities are $V_B$ and $Z_B$ for the other tube. Then:

Consider a configuration of $n$ identical units, each consisting of three layers. The first layer is a column of air of height $h=\frac{1}{3} cm$, and the second and third layers are of equal thickness $d=\frac{\sqrt{3}-1}{2} cm$, and refractive indices $\mu_1=\sqrt{\frac{3}{2}}$ and $\mu_2=\sqrt{3}$, respectively. A light source $O$ is placed on the top of the first unit, as shown in the figure. A ray of light from $O$ is incident on the second layer of the first unit at an angle of $\theta=60^{\circ}$ to the normal. For a specific value of $n$, the ray of light emerges from the bottom of the configuration at a distance $l=\frac{8}{\sqrt{3}} cm$, as shown in the figure. The value of $n$ is. . . . .
