Homework Statement
Why must F2=P2(deltaA)(-j hat) and the opposing force be F1=P1(deltaA)(+j hat). Prove that these are the only two possibilities that are true.
Proving F2 and F1: The Only Possibilities
- Thread starter klezzie13
- Start date
In summary, the problem involves a plane inside a container of water, where the force of gravity points downwards and the forces F1 and F2 must point upward and downward respectively. The equations F2=P2(deltaA)(-j hat) and F1=P1(deltaA)(+j hat) are the only two possibilities that are true, and the equation F/A=p or F=Ap relates force and pressure in this situation.

Could you provide the picture of the situation please? Or at least describe the situation with words.

Welcome to PF klezzie13. In addition to explaining the problem better, you'll need to complete the Relevant equations and attempt at a solution portions of the homework template.

you have a plane inside of a container of water. On the plane there is the force of gravity pointing downward. F2 must point downward and F1 must point upward. There is no acceleration within the system. F1,2≈ P1,2ΔA. Does that help?

I think we need to see the figure.

here it is. Its pretty simplistic but hopefully you get the point.

F/A=p
F=Ap
I think I figured it out
F=Ap
I think I figured it out

Yup, looks like you probably have 
1. What are F2 and F1 in the context of this topic?
F2 and F1 refer to the two possible outcomes in a binary experiment, where F2 represents a failure or negative outcome and F1 represents a success or positive outcome.
2. How is it possible to prove that F2 and F1 are the only possibilities?
This can be proven using the Law of Excluded Middle, which states that a statement is either true or false, there is no middle ground. Therefore, if F2 and F1 are the only two possibilities, then any other outcome is impossible.
3. Can this be applied to all experiments or situations?
Yes, the concept of only two possibilities can be applied to any binary experiment or situation. However, it may not be applicable to experiments with more than two possible outcomes.
4. What evidence or methods can be used to prove F2 and F1 as the only possibilities?
Various mathematical and logical proofs can be used to demonstrate that F2 and F1 are the only possibilities. These may include the use of truth tables, deductive reasoning, and logical syllogisms.
5. Why is it important to understand and prove F2 and F1 as the only possibilities?
Understanding and proving F2 and F1 as the only possibilities can help in decision-making and problem-solving, as it allows for a clear understanding of the potential outcomes. It also helps in identifying any potential biases or assumptions in the experiment or situation.
