A positive charge q is released from rest at the origin of a rectangular coordinate system and moves under the influence of the electric field What is the kinetic energy of q when it passes through
A particle of charge and mass m is placed at the center of a uniformaly charged ring of total charge Q and radius R. The particle is displaced a small distance along the axis perpendicular to the plane of the ring and released. Assuming that the particle is constrained to move along the axis, show that the particle oscillates in simple harmonic motion with a frequency

The circular arc shown below carries a charge per unit length where is measured from the x-axis. What is the electric field at the origin?
Calculate the electric field due to a uniformly charged rod of length L, aligned with the x-axis with one end at the origin; at a point P on the z-axis.
The charge per unit length on the thin rod shown below is What is the electric force on the point charge q? Solve this problem by first considering the electric force on q due to a small segment of the rod, which contains charge Then, find the net force by integrating over the length of the rod.
