You have a hoop of charge of radius R and total charge -Q. You place a positron at the center of the hoop and give it a slight nudge in the direction of the central axis that is normal to the plain of the hoop. Due to the negative charge on the hoop, the positron oscillates back and forth. Step 1: Clearly show how to use integration to find the z-axis E-field of a ring charge. Step 2: Place a...

3 points) An electron is constrained to move along the central axis of a ring of radius R which is uniformly charged with total positive charge Q (a) Show that if the electron is near the centre of the ring (a small distance compared to R), it will experience a force of the form Fz--kz (where z is the distance from the centre of ring) (b) Since this force will make the electron follow simple harmonic oscillation, derive a formula...

The electric field on the axis of a ring of charge near its center( which is located at z=0) is given by E(z)= ((kQ)/(R^3)) z. The ring has a radius R=5 and total charge of Q= 1 uC 1. A charged particle (m = 1 mg, q = –1 nC) is placed near the center of the ring. Write down and expression for the force F(z) that acts on the particle, in terms of kC, Q, q, R and z....

(a) Calculate the electrostatic force on a uniformly charged rod of length 2l, and charge q which lies along the axis of a uniformly charged ring of radius R and charge q'. The centers of the charged rod and the rings are displaced by z = z0. (b) Show that if z0 >> l, is satisfied, then the expression of calculated force reduces to that between point charges.

14. S Review. Two identical particles, each having charge +q, are fixed in space and separated by a distance d. A third particle with charge -Q is free to move and lies initially at rest on the perpendicular bisector of the two fixed charges a distance xfrom the midpoint between those charges (Fig. P23.14). (a) Show that if x is small compared with d, the motion of -Q is simple harmonic along the perpendicular bisec- tor. (b)...

For my lab a 50g mass is on a spring. The spring is pulled down
a different length for each trial and then released. What would the
amplitude of motion be for this experiment and how can I test that
the frequency is independent from the amplitude.
In cases where the restoring force is proportional to the amount of displacement from the oquilibrium position, the object undergoes simple harmonic motion (SHM). An object on a spring is the simplest example...
A block having mass m and charge +Q is connected to an insulating spring having a force constant k.
A block having mass m and charge +Q is connected to an insulating spring having a force constant k. The block lies on a frictionless, insulating, horizontal track, and the system is immersed In a uniform electric field of magnitude E directed as shown in the figure below. The block Is released from rest when the spring Is unstretched (at x = 0). We wish to show that the ensuing motion of the block is simple harmonic. (a) Consider the system...
