Direction of particle between two plates
AI Thread Summary
The discussion revolves around a homework problem involving the motion of a particle between two plates, where the force of the electric field exceeds the gravitational force, causing the particle to accelerate upwards. The original poster expresses confusion over their answer not matching the model solution and seeks clarification on potential mistakes. Other participants confirm that the calculations and conclusions appear correct. Ultimately, the original poster finds their answer to be correct after further review. The exchange highlights the importance of verifying calculations in physics problems.
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
F1=(5000+200)g=5200*10=52000N --> F2=(5000+100)g=5100*10=51000N ?
