Calculating the Number of Electrons Removed from a Coin to Acquire a Charge of 10-6 Coulomb

To find the number of electrons that need to be removed from a coin in order for it to acquire a charge of 10-6 Coulomb, we can use the fundamental charge of an electron and the equation Q = ne, where Q is the charge, n is the number of electrons, and e is the elementary charge.

Given:
Charge (Q) = 10-6 C

Solution:

We can rearrange the equation Q = ne to solve for n:
n = Q / e

The elementary charge, e, is equal to 1.6 x 10-19 C.

Substituting the given values into the equation:
n = (10-6 C) / (1.6 x 10-19 C)

To simplify the calculation, we can divide both the numerator and denominator by 10-19:
n = (10-6 C) / (1.6 x 10-19 C) = (1013) / (1.6)

Simplifying further:
n = 6.25 x 1012

Therefore, the number of electrons that need to be removed from the coin is approximately 6.25 x 1012.

Summary:
To acquire a charge of 10-6 Coulomb, approximately 6.25 x 1012 electrons need to be removed from the coin.

Similar Class 12 Doubts

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?
