a uniform field is oriented toward the right and has a magnitude 54_N/C in which direction will the electron move once it is released at rest? Find the speed of the electron after it has moved .24m?
direction of motion of electron must be opposite to the direction of field, so to the left
acceleration acts on electron
a = eE / m = 1.6* 10^-19* 54 / ( 9.11* 10^-31) = 9.484* 10^12 m/s^2
now using 3rd equation of motion
v^2 = 2 a d = 2* 9.484* 10^12* 0.24
v = 2.133* 10^6 m/s

comment in case any doubt, will reply for sure.. goodluck
