Physics Homework Problem -
Problem 1 - An electron is launched at a 45o angle and a speed of 5.0 x 106 m/s from the positive plate of the parallel plate capacitor shown in the figure. The electron lands 4.0 cm away.
Part A - What is the electric field strength inside the capacitor?
Part B - What is the smallest possible spacing between the plates?
Problem 2 - A positron is an elementary particle identical to an electron except that its charge is +e. An electron and a positron can rotate about their center of mass as if they were a dumbbell connected by a mass-less rod.
Part A - What is the orbital frequency for an electron and a positron 1.70 nm apart?

In this assignment we have encountered few particle physics problems composed with classical physics rules. Though the considered particles are best treated in quantum mechanics but they are in the continuum region and such type project work is very helpful to understand the atomic physics, where classical laws go well with subatomic particles.
Please make sure the tutor draw the FBD, like the graph, that is cause a lot of point. Express your answer with the appropriate units. Read and translate the problem statement - A clear translation of the problem is given. State applicable laws and what assumptions/simplifications allow them to be used in this situation - Correct assumptions/ simplifications are given and related to how they allow the concepts/laws to be used to solve this particular situation.
Represent physically - A clearly labeled, correct physical representation is given, with all relevant quantities clearly defined. Represent the concepts/laws mathematically - A mathematical representation is given in symbols with no numbers. Work through the mathematics - A complete solution with clear mathematical steps is given, and the answer has correct units. Evaluate the result - A clear and complete explanation is given for why the result makes sense (or does not make sense if the incorrect answer was reached), and what it tells us about the physics of the situation.
