The earth has not only a magnetic field (which directs your compass), but an atmospheric electric field. During days of fair weather (no thunder clouds), this atmospheric field has a strength of about 100 N/C and it points down. a) What force would a single electron experience if placed in this field?
If this electron was on a dust particle with a mass of 1.0 x 10-18 kg, what would the net force (electric and gravitational)on the particle be?
