  1. You are asking four different questions. The Earth's magnetic field near the equator will be in a south-to-north direction, more or less. (See
    (Broken Link Removed)

    In each case, the "q V" vector of the electron will be opposite to the direction of V. To get the direction of the force, which is the direction of the deflection, determine the vector cross product (qV) x B
    For (a), qV is up and B is north; so, using the right hand rule, the electron deflection is west.
