What radius circular path does an electron travel if it moves at the same speed and in the same magnetic field as
the proton in Exercise 22.13?
(Ex 22.13- A proton moves at 7.50×10⁷ m/s perpendicular to a magnetic field. The field causes the proton to travel in a
circular path of radius 0.800 m. What is the field strength?)
a.4.36 m
b.40.4 X 10⁻⁴ m
c.9.36 X 10⁻⁶ m
d.4.36 X 10⁻⁴ m
