The Wide belt of the school bag produces less pressure than all the other given options.
The other given 3 options like the needle, sharp knife and spear have narrow ends which are sharp and therefore, they put on more pressure when it touches the skin.
However, the wide belt of the school bag has a broader surface area. As per the formula, P = f/a, the pressure is inversely proportional to area. Therefore, the wider the surface area, lesser is the pressure.
So, from the given options, the wide school belt produces less pressure than others.

Among the given options wide school belts produces less pressure.
Explanation:
1. Pressure= Force/area
2. If area of contact increases then pressure decreases and vice versa
3. Here school bag belt has more surface area hence pressure applied will be less.
4. Hence we don't feel strain on back when we are carrying school bag.
