The cafepress line up of wall clocks is huge and ever growing delivering a large variety of unique decorative clocks for your home or office.
There is a block against the wall wall on right and there is a force pushing on the middle of the block at an angle of 43 degrees clockwise from south.
In this case gravity does not actually push the block into the wall and the force of m g is acting perpandicular to the wall which means only the horizontal force of 12n is acting to be a multiplier in the friction equation.
You might think this is just a boring physics problem but you d be wrong.
This force can either push the block upward.
