An electron has a velocity v = (2 x 10 m/s)i + (3.0x 10 m/s) j moves through a uniform magnetic field B = (0.030 T) i - (0.15 T) j. (a) Find the force on the electron due to the magnetic field. (b) mass of electron is 9.11 x 10 3 kg what will be the radius of the circular path for the electron in the magnetic field
