An electron moves in a uniform circular motion under the action of an external magnetic field perpendicular to the circular path. Consider that the charge and mass of the electron are respectively q = 1.6 x 10-¹9 C, m = 9.11 10-31 Kg, the velocity of the electron is v = 2.8 x 107 and the magnitude of the external magnetic field is B = 2.1 x 10-³T. Calculate the radius R of the circle formed by the electron in its path during its displacement and choose the correct option. 5.5 cm O 7.5 cm 9.5 cm 3.5 cm
