Asmall charged bead has a mass of 1.0 g. it is held in a uniform electric field of magnitude e = 200,000 n/c, directed upward. when the bead is released, it accelerates upward with an acceleration of 20 m/s2. what is the charge on the bead?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
