Question: A particle with charge 7.80 C is moving with velocity u = - (3.80 X l03 m/s) j. The magnetic force on the particle is

A particle with charge 7.80 µC is moving with velocity u = - (3.80 X l03 m/s) j. The magnetic force on the particle is measured to be F = + (7.60 X l0-3N) i - (5.20 X l0-3N) k.
(a) Calculate all the components of the magnetic field you can from this information.
(b) Are there components of the magnetic field that are not determined by the measurement of the force? Explain
(c) Calculate the scalar product B. F what is the angle between B and F?
