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 = 1.88·10-28 kg). Suppose a strong magnetic field is established in a lab (B = 0.417 T) and a muon enters this field with a velocity of 2.41·106 m/s at a right angle to the field. What will be the radius of the resulting orbit of the muon?
An electric field greater than about 3x10^6 V/m causes air to break down (electrons are removed from the atoms and then recombine, emitting light). Estimate the voltage between your finger and the doorknob
