If a particle is traveling straight through a material with index of refraction n at a speed v, what is the angle θ between the vector of the propagating Cerenkov radiation and the vector in the direction of the propagating particle?
Use these constraints and the equation for θ from Part A to determine which of the following substrate materials is best suited to giving you the greatest precision in determining particle velocity
What is the highest velocity at which a charged particle can be accurately measured to be below the speed of light in vacuum (c)

Part A = smooth
Part B = a distance 2h/3 above the floor
Part C = -2mgh/3
Part D = -mgh
Part E = 1/2mvi^2 + mghi = 1/2mvf^2 + mghf

Part A = out of the plane of the figure
Part B = The rod will accelerate but the magnitude of the acceleration will decrease with time; the velocity of the rod will approach but never exceed a certain terminal velocity.
Part C = (V – B * L * vr(t)) * (L * B) / (R * m)
Part D = V / (B * L)
There is a uniform magnetic field of magnitude B, pervading all space, perpendicular to the plane of rod and rails. The rod is released from rest, and it is observed that it accelerates to the left. In what direction does the magnetic field point?
Assuming that the rails have no resistance, what is the most accurate qualitative description of the motion of the rod?
What is the acceleration ar(t) of the rod? Take m to be the mass of the rod.
What is the terminal velocity vt reached by the rod?
