Question

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 unit-vector 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?

Answer 1

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.

Answer 2

*is given by E=(3000i-600j) N/C
the question doesnt include whether x or y is perpendicular to the places
