At some instant the velocity components of an electron moving between two charged parallel plates are vx = 1.5 × 105 m/s and vy = 3.0 × 103 m/s. Suppose the electric field between the plates is given by In unitvector notation, what are (a) the electron's acceleration in that field and (b) the electron's velocity when its x coordinate has changed by 2.0 cm?

You have left out an important number after
"Suppose the electric field between the plates is given by ..."
You also need to say whether x or y is perpendicular to the places. 
*is given by E=(3000i600j) N/C
the question doesnt include whether x or y is perpendicular to the places
