Question

28. The force acting on a unit
area of a surface is called
O Force
O None of these
O Density
O Pressure​

Answer 1

Answer:

The force acting on a unit area of a surface is called pressure. Hence, the correct option is (B) pressure. ... For example, if a perpendicular force of 10N is acting on one side of cube with surface area of each side equal to 5m2 then the pressure (P) exerted on it is P=perpendicular forcearea=105=2Nm−2.

Answer 2

Answer:

Force per unit area is defined as the pressure. If 1 N of force is acting over an area of 1 m2, then it would be called unit pressure or pressure of 1 Pa.
