Question

If only the thrust acting on an object is doubled, the pressure on the surface:

• A. Reduces by half
• B. Triples
• C. Doubles
• D. Remains the same

Answer 1

The correct option is C Doubles

Pressure is defined as the thrust acting on a body per unit area:
$\text{Pressure}=\frac{\text{Thrust}}{\text{Area}}$

Hence, if the thrust acting on an object is doubled (keeping the area constant), the pressure acting on the surface would also be doubled.
