Force on a moving charge inside magnetic field is given by
[tex]F = q(v x B)[/tex]
So as per right hand rule if we put our fingers of right hand along the velocity of charge and then curl it towards the magnetic field direction then thumb will show the direction of force on moving charge.
Above rule is known as right hand rule.
If we use the same for the given condition then velocity is given out of the plane and magnetic field is downwards then as per right hand rule direction of force on the moving charge will be "Towards Right"
