Question

Consider a particle velocity filter.  The uniform E and B fields are oriented perpendicular to each other.

An electron moves with a speed of 9.6*10^6 m/s at the right angles to both E and B fields, and passes through the fields undeflected.

a) If the magnitude of E is 2.2 kV/m, what is the magnitude of B?

b) Will this filter work for both positive and negative charges, and for any value of mass?  What theory or explanations would support this?
