Answer:
Assertion - Nails and pins have pointed ends. This is true
Reason - Pressure is inversely proportional to area for the same for so that this can be fixed with maximum force. This is also true
Pins and nails have sharp and pointed ends, which decreases the area. As pressure is inversely proportional to area therefore, less area will be equal to more pressure. As the pins and nails have less area, therefore they will apply a greater pressure on the object and pierce that object easily.
