Answer
Case 1 : Price Floor
Case 2 : Price Ceiling
Work Step by Step
Case 1:
In case 1, the price floor is shown above the equilibrium as represented in the diagram .
At this price it will create a surplus of $(Q_{s}-Q_{d})$.
Case 2:
In case 2, the price ceiling is shown below the equilibrium as represented in the diagram.
At this price, it will create a Deficit of $(Q_{d}-Q_{d})$.
