An electron traveling north enters a region where the electric field is uniform and points east. Will the electron speeds up or slows down?

electron has a constant velocity in the north direction and accelerates in the west direction, the electron is accelerating and its velocity on this axis increasing in the west direction.

Explanation:

In this exercise we are asked about the speed of the electron

The electric force is F = q E

the charge of the electron is q = -e = - 1.6 10-19 C

If we use Newton's second law

Y axis (North-south direction)

        = cte

X axis (East-West direction)

      F = m a

     - e E = m a

      a = - e / m E

whereby electron has a constant velocity in the north direction and accelerates in the west direction, the electron is accelerating and its velocity on this axis increasing in the west direction.
