The Earth is showered with particles from space known as muons. They have a charge identical to that of an electron but are many times heavier (m=1.88?10?28kg ). Suppose a strong magnetic field is established in a lab (B=0.500T ) and a muon enters this field with a velocity of 3.09?106m/s at a right angle to the field.
What will be the radius of the muon's resulting orbit?
