# Point Charge in Electric Field

## Homework Statement

See figure attached for problem statement.

## The Attempt at a Solution

I think my main source of confusion is this problem is how the force is acting on the electron.

The picture shows that the electric field is pointing straight up, but since its acting on an electron (negative charge) the force will be in the opposite direction correct? (i.e. straight down)

If this is the case the acceleration the electron experiences is a vertical acceleration downwards.

Anyways, here's my attempt at the problem,

Did I make any mistakes?

Check your calculation for Vyfinal, A is downwards and therefore negative
