A particular type of fundamental particle decays by transforming into an electron e- and a positron e (same amount of charge as e- but with positive sign). Suppose the decaying particle is at rest in a uniform magnetic field B of magnitude 3.53 mT and the e- and e move away from the decay point in paths lying in a plane perpendicular to B. How long after the decay do the e- and e collide

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
