alleryStart learning →Pressure is defined as
AThrust times area of the surface
BThrust acting per unit area
CMass divided by volume of the body
DForce times distance moved
Answer & Solution
Correct answer: B. Thrust acting per unit area
1. Pressure compares the effect of thrust on different areas.
2. Smaller area concentrates the thrust and gives more pressure.
3. Mathematically pressure = thrust / area.
4. So option A is correct.
