At time t a magnetic field B = 0.200 T in the +2-direction exerts a force on the electron equal to F = 5.50 x 10-10N in the -y-direction. What is the magnitude of velocity of the electron at this instant? Express your answer with the appropriate units. HA FOE ? Value Units Submit Request Answer Part B What is the direction of velocity of the electron at this instant? The velocity of the electron would have to be in the +r-direction. O The velocity of the electron would have to be in the -I-direction. Submit Request Answer
