Homework Statement


2 parallel plates of length 4.0 cm are arranged horizontally in a vacuum. The upper plate is positively charged and the lower plate is negatively charged. An electron is projected horizontally with an initial velocity of 6.0 x 106 ms-1 and experiences a constant electric force of 3.4 x 10-17 N whilst between the plates. Negating any gravitational effects, find the angle the electron makes with the horizontal on leaving the plates.

Homework Equations


Not that I know of

The Attempt at a Solution


The electron experiences an attractive force of 3.4 x 10-17 N towards the positively charged plate. I don't know the horizontal component of the force acting on the electron so I can't calculate the resultant force.

What makes you think there is a horizontal component or force?

you know the horizontal VELOCITY..can you calculate the time that the electron is between the plates?
