Question

F Penny's piston is wider than Pauly's, who is pushing with greater force?

Answer 1

A Penny is exerting the greater force.
 B Pauly is exerting the greater force.
C They are both using equal force.
Think its A or C

Answer 2

It would depend on who is stronger but it is likely that Penny would be creating larger pressure because the surface area is less. If this is part of a question where the pressure for both is the same then Pauly is pushing with greater force, I know this because force/area=pressure and when the surface area is larger the force must be greater as well.

Hope this helps :)
