Explanation:

To find the Coulomb force between two electrons at the same distance, we need to apply Coulomb's law. Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Let's assume the charge on an electron is 'e'. Then the charge on a proton would be 'e' as well, but opposite in sign. The mass of a proton is 1836 times greater than the mass of an electron.

Let's consider the force between two protons at a certain distance. According to Coulomb's law,

F = k * (q1 * q2) / r^2

Where:
F = Coulomb force
k = Coulomb's constant
q1 = charge of proton (e)
q2 = charge of proton (e)
r = distance between protons

Now, let's consider the force between two electrons at the same distance. According to Coulomb's law,

F' = k * (q1 * q2) / r^2

Where:
F' = Coulomb force between electrons
q1 = charge of electron (e)
q2 = charge of electron (e)
r = distance between electrons

Since the charge on an electron is the same as the charge on a proton, we can write q1 = q2 = e in both cases.

Comparison:
Comparing the two equations, we can see that the only difference is in the masses of the particles:

For protons: F = k * (e * e) / r^2
For electrons: F' = k * (e * e) / r^2

Since the masses of the particles do not appear in the equations, the force between two electrons for the same distance would be the same as the force between two protons. Therefore, the correct answer is option 'A', F.

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescences microscopy.Q. Why electron as wave is used in electron microscope to illuminate the sample?
