A proton collides elastically with another proton that is initially at rest. The incoming proton has an initial speed of 4.60 105 m/s and makes a glancing collision with the second proton as in the figure. (At close separations, the protons exert a repulsive electrostatic force on each other.) After the collision, one proton moves off at an angle of 31.2° to the original direction of motion and the second deflects at an angle of to the same axis. What if two electrons are used instead? One electron comes in at a speed 4.3 106 m/s, while the second one was at rest initially. After the glancing collision, the first electron moves off at an angle 19°. Find the final speeds of the two electrons.
In daily life we see many cases of people who are caught misrepresenting things who soon thereafter are excused and accepted by their contemporaries. How is This different in science.
