A block of mass `4kg` is placed on the inclined surface of wedge of mass `12 kg`. A horizontal force `"F"` is applied on the surcface of wedge as shown in figure (Direction of force may be along the positive and negative x-axis) . All of the contact surfaces are smooth. Magnitude of force applied on the wedge `"F"`, Normal contact force between wedge and block `"N"` and acceleration of block `"a"` are given in Column 1, 2 and 3 respectively. Consider horizontal axis is along the x -axis and vertical axis is along the y -axis.

In which of the following case acceleration of block is in horizontal direction?
