Radio astronomers detect electromagnetic radiation at 50.0 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?

0.00178 T

Explanation:

f = Frequency = 50 MHz

m = Mass of electron =

q = Charge of electron =

In circular motion the magnetic field is given by

The magnetic field strength inside the gas cloud is 0.00178 T

i think the answer is a, hope this : )

i had this question and the answer was 3.15 miles.
