A finite rod of length L has total charge q, distributed uniformly along its length. The rod lieson the x-axis and is centered at the origin. Thus one endpoint (x, y) is located at (-L/2, 0)and the other is located at (L/2, 0). Define the electric potential to be zero at an infinitedistance away from the rod.
Q: What is VB, the electric potential at point B, located at distance d from one end of therod (on the x-axis)?
Two charged objects 1 and 2 are held at a distance r apart. Object 1 has mass m and charge+2q, and object 2 has mass 2m and charge +q. The objects are released from rest. Assumethat the only force exerted on either object is the electric force exerted by the other object.
Q1: When the objects are in motion, what is the ratio of their kinetic energies K2/K1?
Q2: When the objects are at a distance 4r apart, what is the speed of object 1? What aboutthe speed of object 2?
Q3: When the objects are very far apart, what are their speeds?
