MCQ
In the given circuit, with steady current, the potential drop across the capacitor must be
  • A
    $V$
  • B
    $V/2$
  • $V/3$
  • D
    $2V/3$

Answer

Correct option: C.
$V/3$
c
in sleady state

$I=\frac{2 V-V}{2 R+R}=\frac{V}{3 R}$

Potential differnce across $"\mathrm{R}"$ $=\frac{\mathrm{V}}{3 \mathrm{R}} \times \mathrm{R}=\frac{\mathrm{V}}{3}$

$\therefore \mathrm{V}_{\mathrm{AB}}=\mathrm{V}+\frac{\mathrm{V}}{3}$

and

So potential difference across $\mathrm{C}=\frac{\mathrm{V}}{3}$

When a particle is restricted to move along $x$-axis between $x=0$ and $x=a$, where $a$ is of nanometer dimension, its energy can take only certain specific values. The allowed energies of the particle moving in such a restricted region, correspond to the formation of standing waves with nodes at its ends $x=0$ and $x=a$. The wavelength of this standing wave is related to the linear momentum $p$ of the particle according to the de Broglie relation. The energy of the particle of mass $m$ is related to its linear momentum as $E=\frac{p^2}{2 m}$. Thus, the energy of the particle can be denoted by a quantum number ' $n$ ' taking values $1,2,3, \ldots \quad(n=1$, called the ground state) corresponding to the number of loops in the standing wave.

Use the model described above to answer the following three questions for a particle moving in the line $x=0$ to $x=a$. Take $h=6.6 \times 10^{-34} \mathrm{~J} \mathrm{~s}$ and $e=1.6 \times 10^{-19} \mathrm{C}$.

$1.$ The allowed energy for the particle for a particular value of $n$ is proportional to

$(A)$ $a^{-2}$ $(B)$ $a^{-3 / 2}$ $(C)$ $a^{-1}$ $(D)$ $a^2$

$2.$ If the mass of the particle is $m=1.0 \times 10^{-30} \mathrm{~kg}$ and $a=6.6 \mathrm{~nm}$, the energy of the particle in its ground state is closest to

$(A)$ $0.8 \ \mathrm{meV}$ $(B)$ $8 \ \mathrm{meV}$ $(C)$ $80 \ \mathrm{meV}$ $(D)$ $800 \ \mathrm{meV}$
