If the positive charge is placed at rest in the cylindrical region, It will not move at all.

The magnetic force on a stationary charge is zero.

This is the case if the positive charge is placed at the center of cylindrical region. If not, the direction of the E field is azimuthal and proportional to the distance form the center. The charge will start to move in a direction perpendicular to both the B field and the direction from which it is away from the center.
