• B. sharp knife exerts less pressure
• C. both knives exert equal pressure
• D. sharp knife has a better grip

Answer 1

The correct option is A sharp knife exerts more pressure

It is easier to cut with a sharp knife than with a blunt one,
Blunt Blades have larger area compared to the sharp-edged blade.
Thus the applied force produces a lower pressure in case of blunt blades, which makes it difficult to cut the object.
