Multiple Choice

Use the following figure for the next problem.
-The electrons coming out of the electron gun in an electron microscope are being accelerated by a potential of 100 kV.The electrons then pass through a region of magnetic field of distance y = 8 cm which points perpendicularly to the direction of travel of the electron.What is the strength of the magnetic field needed to deflect the electron by an angle of $\theta$ = 25 ^$\circ$ ? (Ignore any relativistic effect.1 Gauss = 10^-4 T)

• A)120.1 Gauss
• B)30.4 Gauss
• C)21.8 Gauss
• D)14.6 Gauss
• E)None of these is correct.

Definitions:

Standard Deviations

It is a statistic that quantifies the dispersion or spread of a dataset relative to its mean, indicating how spread out the data points are.

Observations

The collection of data or information obtained through watching, measuring, or recording something.

Coefficient Of Kurtosis

A statistical measure that describes the shape of a distribution's tails in relation to a normal distribution.

Dispersion

A measure of the spread of a distribution, indicating how far the data points are from the mean.
