Chapter 23 Energy is conserved, so the change in potential energy
... 30. By energy conservation, all of the initial potential energy of the charges will change to kinetic energy when the charges are very far away from each other. By momentum conservation, since the initial momentum is zero and the charges have identical masses, the charges will have equal speeds in o ...

... Assume an electron (mass m=9.109e-31 kg, charge q=-1.602e-19 C) is initially located in the plane at (x0,y0) and released with an initial velocity (vx0, vy0). a) Write a routine to determine the position as a function of time for the electron. You should be solving for x(t), y(t), vx(t), and vy(t). ...

(unbent) area of the net, how many fish per hour will be caught with
... There is nothing in Coulomb’s law that argues against a “fish picture” of electric fields. If we count fish flowing from a + charge, we should get the same number of fish if we capture them 1 m away, or 10 m away. Coulomb’s law says we do. (In fact, all of electromagnetic theory and experiment is c ...
