A drawing pin (thumb tack) has one end with a sharp point and the other end with a flat surface. It is pressed into a wooden board. How do the pressure and the force at the sharp point compare with the pressure and the force on the flat surface?
- Aforce at the sharp point greater than on the flat surface; pressure at the sharp point greater than on the flat surface
- Bforce at the sharp point greater than on the flat surface; pressure at the sharp point less than on the flat surface
- Cforce at the sharp point the same as on the flat surface; pressure at the sharp point greater than on the flat surface
- Dforce at the sharp point the same as on the flat surface; pressure at the sharp point less than on the flat surface
