Use Fleming's left-hand rule. The direction of current is shown by the middle finger, the direction of magnetic field is shown by the index finger and the thumb will show the direction of motion of the particle.
Hence, we can see that the middle finger is directed from North to South, the index finger is directed downwards. Therefore, the thumb will be directed eastwards. So, the electron will move towards East.
