(b) Assume the particles are released simultaneously. Describe the subsequent motion of each. Will any collisions take place? Explain.
An electron has an initial velocity of 3.6x104 m/s to the right. It then travels through a potential difference, which speeds the electron up to a velocity of 8.1x104 m/s to the right. a) Since the particle was traveling to the right, and sped up, what was the direction of the acceleration of the electron, left or right? b) What then must have been the direction of the force on the electron? c) And then what must have been the direction of the electric field in that area? d) Given that you know the electric field has to point from high potential to low potential, is the electron traveling from a low to a high potential, or is it traveling from a high to a low potential? e) Does that make the potential difference (the change in potential) positive, or negative?
Two electrons in a vacuum exert force of F = 4.63E-08 N on each other. They are then moved so that they are separated by x = 6.4 times their original distance. a.

What does the term reference configuration mean in the context of gravity? b. Suppose a system consists of an apple and the Earth, with the reference configuration set so that the systems gravitational potential energy is zero when the apple is on your desk. If the apple is above the desk, is the potential energy positive, negative, or zero? c. What is the conventional reference configuration for universal gravity? Why is that a convenient reference configuration? If a system consists of an apple and the Earth, does the systems gravitational potential energy increase, decrease, or stay the same as you raise the apple upward?

An electrically charged particle is held at rest at the point x = 0; a second particle with equal charge is free to move along the positive x-axis. The potential energy of the system is U1x2 = C/x, where C is a positive constant that depends on the magnitude of the charges. Derive an expression for the x-component of force acting on the movable particle as a function of its position.
