Question

The bags and suitcases are provided with broad handles so that the extended on the hand while carrying them is minimum.
(A) Pressure
(B) Thrust
(C) Force
(D) Friction

Answer 1

Hint Pressure is the ratio of force to area. From this relation we know that pressure is inversely proportional to the area. When the handles are wider it means that the surface area is more so the pressure acting is less.

Complete step-by-step solution
Out of the four options we know that pressure is a physical quantity defined as the force per unit area. So, surface area is a factor affecting pressure.
Pressure is the ratio of force acting to the surface area
 $P = \dfrac{F}{A}$
From the relation pressure is inversely proportional to the surface area which means as area decreases pressure increases and pressure decreases with the increase in surface area.
 $P \propto \dfrac{1}{A}$

Hence, the reason for broad handles is that pressure can be minimum.

The correct option is A.

Note: The same above explanation holds good for why the edge of the knife has a small area, the nails are small and narrow pointed, pointed heels over flats, walking versus standing still and more.
