(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Earth exerts a downward gravitational force of 8.9 N on a cake that is resting on a plate. The plate exerts a force of 11.0 N upward on the cake. [ add the rest of the problem: and a knife exerts a downward force of 2.1 N on the cake. Draw a free-body diagram of the cake.]

3. The attempt at a solution

My question here is that i know 8.9 N is the cake's weight, and this force is pointing downward, but why then the force from plate pointing upward is 11.0N not 8.9 N equally?

thank you.
