A charged bead with a mass of 3 g isinjected into a uniform electric field E = 4.00 x 104N/C j (meaning up). The bead's initial velocity is 16 m/s i. If theobserved acceleratin of the bead is -2.3 m/s j and the bead movesthrough the field for 3.8 s, A) what is the charge on thebead?   B) What is the beads final velocity?
