Upside down Inclined plane problem

Lets imagine that there is an inclined plane with 30 degrees and a woden Block on it. Now you turn the plane over so the horizontal becomes vertical. The koeficient of friction between Wood Block and plane is 0.3. What should be the size of aceleration in horizontal direction, such that Wood Block stays slide down with uniform velocity.

Just a little clarification;

Now you turn the plane over so the horizontal becomes vertical.
Do you mean that you turn the plane through 90deg so that you end up with an inclined plane at 60 degrees (horizontal becomes vertical)?
or do you turn everything upside down (turn the plane over) so that the block is hanging under the inclined plane?

You turn everything. So the Block is hanging down.

This is the picture. What should the aceleration to the right be so the block slide down uniformely
