Week 4 Physics 272 Recitation, Spring 2019 Problem: You and your friend are discussing last week's recitation problem, in which an electron falling down a tunnel through a uniformly charged earth exhibits simple harmonic motion. Instead of being uniformly charged, imagine that the Earth is given a spherically symmetric charge density p(r)-b/r, where b is some constant. If an electron is released from rest inside this tunnel at some initial distance from the center, find an expression for the acceleration...

In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of the particles scattered almost directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to propose the existence of a very dense concentration of positive charge at the center of an atom—the atomic nucleus. The alpha particle has a charge of +2e and the gold nucleus...

Problem 3 The residents of a small planet have bored a hole straight through its center as part of a communications system. The hole has been filled with a tube and the air has been pumped out of the tube to virtually eliminate friction. Messages are passed back and forth by dropping packets through the tube. The planet has a density of 4210kg/m3, and it has a radius of R-5.87x10m. What is the speed of the message packet as it...

Consider a ring of radius R with the total charge Q spread uniformly over its perimeter. a. What is the potential difference between the point at the center of the ring and a point on its axis a distance 15R from the center? (Use any variable or symbol stated above along with the following as necessary: k.) ΔV = V15R − V0 =_______________ b. Suppose the ring has a charge of +100 μC and a radius of 0.1m. Imagine placing...

ReviewI Constants The nucleus of a 12 Xe atom (an isotope of the element xenon which has a total of 125 protons and neutrons) is 6.0 fm in diameter. (1 fm = 1 femtometer = 1 × 10-15 m) Xenon has 54 protons, therfore, the nucleus has total charge q = +54e. Another proton (which is not part of the Xenon nucleus) is placed a distance d 9.0 fm from the surface of the nucleus. (Figure 1) Part A What...

2. A steady, uniform magnetic field B with unknown magnitude and direction exists through- the shaded rectangular region shown here (diagrams are not to scale). This region is planar-entirely in the x-y plane (+x is east and +y is north). The region's width (from its west edge to its east edge) is a known distance D. The region's length (from its north edge to its south edge) is 10D. Consider the following experiments, all performed with this field. coonfinate atan...
