A long rectangular conducting loop of width ' $l$ ', mass ' $m$ ' and resistance ' $R$ ' is placed partly in a perpendicular magnetic field ' B '. It is pushed downwards with velocity ' $V$ ' so that it may continue to fall freely. The velocity ' $V$ ' is

$\frac{\mathrm{mgR}^2}{\mathrm{~B} l}$

$\frac{\mathrm{B}^2 l^2 \mathrm{R}}{\mathrm{mg}}$

$\frac{\mathrm{mgR}}{\mathrm{B}^2 l^2}$

The polarising angle of transparent medium is ' $\theta$ '. Let the speed of light in the medium be ' v '. Then the relation between ' $\theta$ ' and ' $\mathbf{v}$ ' is [ $\mathrm{c}=$ velocity of light in air]

$\quad \theta=\sin ^{-1}\left(\frac{\mathrm{v}}{\mathrm{c}}\right)$

$\theta=\tan ^{-1}\left(\frac{\mathrm{v}}{\mathrm{c}}\right)$

$\theta=\cot ^{-1}\left(\frac{\mathrm{v}}{\mathrm{c}}\right)$

$\quad \theta=\cos ^{-1}\left(\frac{\mathrm{v}}{\mathrm{c}}\right)$
