A force of 90 N acts on an area of 15 cm2. What is the pressure in N per cm2?
Answer and explanation
Correct answer: B. 6 N/cm2
- Step 1: Pressure = force / area. Step 2. 90 / 15 = 6 N/cm2. Answer: 6 N/cm2. Why not the others: 1350 N/cm2: force and area were multiplied. 0.2 N/cm2: the ratio was inverted. 75 N/cm2: area was subtracted from force.
