Question

a force of 25 n act area is 25 CM square calculate the pressure

Answer 1

Pressure=25/25

Pressure is defined as the force acting per unit area surface.

Pressure = force/ area =F/A……1

S.I unit is Nm-2 isalso called 1Pascal (Pa). Pressure is scalar quantity.

Pressure is inversely proportional to the area. i.e. force acting on the small area exerts more pressure.

Pressure is directly proportional to the applied force.i.e. more pressure is exerted if the force is increased and vice-versa.
