Answer:out of the page

Step-by-step explanation:

This can be answered by Lorentz force experienced by a charged particle in a magnetic field

which is given by F=q(vxB)

as the charge is moving in anti-clockwise direction so velocity will be tangential to imaginary circle and the force is acting towards the center so magnetic field is inside the page but the charge is negative so magnetic field is out of page(F is perpendicular to v &B)
