an electron m=9.11x10^-31 kg and q= -1.602x10^-19 C enters a region where th magnetic field is constant and perpendicular to the velocity of the electron. the speed of the electron is v=5x10&m/s. the electron moves in a circle of radius 2cm. a. what is the magnitude B of the magnetic field? b. what is the periods of the circular motion of the electron? what is the frequency of the motion? c. the electron radiates as its moves in a circle and emits radiation. what i s the wavelength of this radiation and characterize this radiation? the frequency of the radiation is the same as the frequency of the circular motion of the electron i would attempt the solution if i knew how to find B. I honestly dont know what to do with this.
