(a) A Pressure is defined as the force per unit area

(b) A The SI unit of pressure by definition is N/m²

(c) A The smaller the area, larger is the pressure on a surface for the same amount of force (the weight of the brick). Hence, the brick A whose area of contact is minimum will exert more pressure on the table.

Thus, option A is the correct answer.

(d) B Greater amount of pressure is exerted on an object if the surface area in contact is lesser for the same amount of force

Mathematically, pressure is described as

If the area is reduced for a fixed amount of force, the magnitude of the pressure increases. Thus, option B is the correct answer.

(e) B The pressure due to a certain force F on a surface of area A,is given as

Since pressure is a scalar quantity, only the magnitude of force is required to calculate pressure.
