An electron e with kinetic energy 1.000 mev makes a head-on collision with a positron e at rest. (a positron is an antimatter particle that has the same mass as the electron but opposite charge.) in the collision the two particles annihilate each other and are replaced by two photons of equal energy, each traveling at angles θ with the electron's direction of motion. the reaction is show that the angle is cos θ--il a) c lity

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
