A force of 1000 N acts evenly on an area of 5 square m. What pressure is exerted?
Answer and explanation
Correct answer: B. 200 Pa
- Step 1: Pressure = force / area.
- Step 2: 1000 / 5 = 200 Pa.
Answer
200 Pa.
Why not the others: 0.005 Pa: area was divided by force. 5000 Pa: force and area were multiplied. 995 Pa: area was subtracted from force.
