Physics for IGCSE & O level - Forces And Pressure (Section 8 - No. 5)
If you double the force applied to an object while halving the area, how does the pressure change?
The pressure remains the same.
The pressure doubles.
The pressure quadruples.
The pressure halves.
Wyjaśnienie
Pressure is Force/Area. If F doubles and A halves, the pressure is multiplied by 4.
