Given: Hz and J
We know that
where J
Therefore,
Converting to electron volts, we get eV
Therefore, the stopping potential is V.

Question 1
A parallel-plate capacitor is placed in such a way that its plates are horizontal and the lower plate is dipped into a liquid of dielectric constant and density . Each plate has area . The plates now connected to a battery which supplies a positive charge of magnitude to the upper plate. Find the rise in the level of the liquid in the space between the plates.

Question 3
Assertion: NAND or NOR gates are called digital building blocks.Easy
Reason: The repeated use of NAND or NOR gates can produce all the basics or completed gates.
Question 4
Light of wavelength falling on a piece of metal ejects electrons with sufficient energy with required voltage to prevent them from reaching a collector. In the same set up, light of wavelength ejects electrons which require twice the voltage to stop them in reaching a collector. The numerical value of voltage isMedium

3. The incident photon interacts with a single electron and loses its energy in two parts:
(i) in releasing the electron from its bondage, and
(ii) in imparting kinetic energy to emitted electron.
Accordingly, if is the energy of incident photon, then from law of conservation of energy
or maximum kinetic energy of photoelectrons,
where is work function. This equation is referred as Einstein's photoelectric equation and explains all experimental results of photoelectric effect. If is stopping potential, then
