A positron (the electron's antiparticle) has mass 9.11 x 10-31kg and charge q0 = +e = +1.60 x 10-19 C. Suppose a positron moves directly away from an alpha particle, which has charge q = +2e. The alpha particle is stationary. When the positron is 1.00 x 10-10 m from the alpha particle, it is moving directly away from the alpha particle at 3.00 x 106 m/s.
(a) What is the positron's speed when the particles are 2.00 x 10-10 m apart?
(b) What is the positron's speed when it is very far from the alpha particle?
(c) Suppose the initial conditions are the same but the moving particle is an electron. Can the electron escape? If not, what is the distance of maximum separation?

A positron has a mass of 9.11 x 10^-31 kg, and charge qp = +e = +1.60 x 10^-19 C. It is moving towards an α particle (qα = +2e, mα = 6.66 x 10^-27 kg) with a speed of 3.00 x 10^6 m/s. At this instant the separation between the two is 2.00 x 10^-10 m. Assume α particle stays at rest. (a) Calculate the speed of positron at 1.00 x 10^-10 m from α particle. (b) What is...

An electron of mass me = 9.11x 10^-31kg and a charge of qe = -1.60 x 10^-19 is released, from rest, in a region of uniform electric field that points to the right with a magnitude of E=3.43 N/C. How long does it take for the electron to reach a speed of 4.49 x 104 m/s? Assume the experiment is performed in a vacuum and that you can ignore the effects of gravity and friction.

Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm

An electron and a positron each have a mass of 9.11 ×
10-31 kg. They collide and both vanish, with only
electromagnetic radiation appearing after the collision. If each
particle is moving at a speed of 0.42c relative to the
laboratory before the collision, determine the energy of the
electromagnetic radiation.
