Radio astronomers detect electromagnetic radiation at 44.0 MHz from an interstellar gas cloud. They suspect this radiation is emitted by electrons spiraling in a magnetic field. What is the magnetic field strength inside the gas cloud?

The magnetic field strength is  

Explanation:

The objective of the solution is to obtain the magnetic field strength inside the gas cloud and in order to do so we would be employing the mathematical expression of magnetic field strength which is represented as

Where B is the magnetic field strength

           f is the frequency

           m is the mass

           q is the  charge

From the question

Generally the mass of an electron which is the is particle

And the charge q is generally

Note that this electromagnetic radiation with frequency 44.0MHz is a moving electron mass

   substituting these values into the equation for the magnetic field strength

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
