Explanation:
We know that the area of sharp edged knife is much less than the area of blunt edged knife. Since pressure = Force/area, therefore for the given force pressure will be more for the sharp edge than for the blunt edge knife. That is why it is easy to cut an apple with a sharp knife than with a blunt knife.
Thanks me much as possible yar
