Well, a few things could happen. Thought it isnt movable, it isnt indestructible, so hence it could simply explode right there. Or, the energy from this force could travel into whatever else the object is touching and it will move, shake, destroy it. If it was sitting in the air hovering, and it wasnt moved, and you couldn't destroy it, the force would probably just exert all its energy into the surrounding air.
Then again I am not a physics expert...so I wouldn't know
