l) The friction force between the block and the wall has magnitude M*g and points to the right.
ll) The friction force between the block and the wall points to the right and has magnitude μeF, where μe is the coefficient of static friction between the block and the wall.
lll) The friction force between the block and the wall points upwards and has magnitude μeF, where μe is the coefficient of static friction between the block and the wall.
IV) The friction force between the block and the wall is zero.
V) The friction force between the block and the wall points downwards and has magnitude μeMg, where μe is the coefficient of static friction between the block and the wall.
Vl) The friction force between the block and the wall points to the right and has magnitude μeMg, where μe is the coefficient of static friction between the block and the wall.
Vll) The friction force between the block and the wall has magnitude Mg and points upwards.
