Vedclass · Answer

(B) It is difficult to hold a school bag with a thin strap because the pressure exerted on the shoulders is very high.Pressure is defined as force per unit area,given by the formula $P = F/A$.Since pressure is inversely proportional to the surface area $(A)$ on which the force $(F)$ acts,a smaller surface area results in a higher pressure.In the case of a thin strap,the contact surface area is very small,which leads to a significantly larger pressure on the shoulder,causing pain and discomfort.
