A ring takes time ${t_1}$ in slipping down an inclined plane of length $L$ and takes time ${t_2}$ in rolling down the same plane. The ratio $\frac{{{t_1}}}{{{t_2}}}$ is

A particle of mass ' $m$ ' and charge ' $q$ ' is fastened to one end ' $A$ ' of a massless string having equilibrium length $\ell$, whose other end is fixed at point ' $O$ '. The whole system is placed on a frictionless horizontal plane and is initially at rest. If uniform electric field is switched on along the direction as shown in figure, then the speed of the particle when it crosses the x -axis is

A light ray is incident on the surface of a sphere of refractive index $n$ at an angle of incidence $\theta_0$. The ray partially refracts into the sphere with angle of refraction $\phi_0$ and then partly reflects from the back surface. The reflected ray then emerges out of the sphere after a partial refraction. The total angle of deviation of the emergent ray with respect to the incident ray is $\alpha$. Match the quantities mentioned in $List-I$ with their values in $List-II$ and choose the correct option.

$List-I$	$List-II$
($P$) If $n=2$ and $\alpha=180^{\circ}$, then all the possible values of $\theta_0$ will be	($1$) $30^{\circ}$ and $0^{\circ}$
($Q$) If $n=\sqrt{3}$ and $\alpha=180^{\circ}$, then all the possible values of $\theta_0$ will be	($2$) $60^{\circ}$ and $0^{\circ}$
($R$) If $n=\sqrt{3}$ and $\alpha=180^{\circ}$, then all the possible values of $\phi_0$ will be	($3$) $45^{\circ}$ and $0^{\circ}$
($S$) If $n=\sqrt{2}$ and $\theta_0=45^{\circ}$, then all the possible values of $\alpha$ will be	($4$) $150^{\circ}$
