An electron enters a magnetic field of 0.64 T with a velocity perpendicular to the direction of the field. What is the value f ×10-10, where f is the frequency (in Hz) at which the electron traverse a circular path? (The mass of an electron is 9.1×10-31 kg and the charge of an electron is 1.6×10-19 C). Express the answer with two decimal places.
