MHT CET 2025 26th April Evening Shift | Electromagnetic Induction Question 1 | Physics

The plot of magnetic flux ' $\phi$ ' linked with the coil versus current ' I ' is as shown in figure for two inductors $\mathrm{L}_1$ and $\mathrm{L}_2$. The self inductance of

$\quad \mathrm{L}_1$ is equal to that of $\mathrm{L}_2$.

$\quad \mathrm{L}_1$ is less than that of $\mathrm{L}_2$.

$\quad \mathrm{L}_1$ is greater than that of $\mathrm{L}_2$.

$\quad \mathrm{L}_1$ is half that of $\mathrm{L}_2$.

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

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

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

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

$\frac{\mathrm{mgl}}{\mathrm{B}^2 \mathrm{R}^2}$
