Question

If a weight of 150 N is applied on a surface of area 10 cm x 10 cm, calculate the pressure acting on the surface.​

Answer 1

Explanation:

$pressure = \frac{force}{area} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{150}{10 \times 10} \\ \: \: \: \: \: \: = 1.5 \: newton \: {cm}^{ - 2}$

Answer 2

Answer:

Pressure = 1500 N/m^2

Explanation:

Pressure = Force ÷ Area

Force = 150 N

Area = 10 x 10 = 100 cm^2

Area = 0.1 m^2

Pressure = F/A = 150/0.1 = 1500 N/m^2
