Calculating Applied force on an inclined plane

What force is required to push a 200N body up a 30 smooth incline with an acceleration of 2m/s2
? The force is to be applied along the plane.

Inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.

so mgCos would be only needed to calculate the friction? would it be Cos 30° ?
