Question
It is difficult to cut cloth using a pair of scissors with blunt blades. Explain.
Solution
It is difficult to cut cloth using a pair of scissors with blunt blades because blunt blades have more area and due to which applied force produces very less pressure. As we know that pressure is inversely proportional to area of cross-section, so it is difficult to cut cloth from blunt blades.
