A constant voltage of $50\text{V}$ is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is:

A photon and an electron (mass $m$) have the same energy $E$. The ratio $({\lambda }_{\text{photon}}/{\lambda }_{\text{electron}})$ of their de-Broglie wavelengths is ($c$ is the speed of light):

Which of the following options represents the variation of photoelectric current with intensity and frequency of light shown on the x-axis?

A sphere of radius $R$ is cut from a larger solid sphere of radius $2R$ as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is:

A full wave rectifier circuit with diodes ($D_1$) and ($D_2$) is shown in the figure. If input supply voltage $V_{in}=220\sin (100\pi t)\text{volt}$, then at $t=15\text{msec}$:
