Chapter 23, Problem 23.88CP
Inez is putting up decorations for her sister’s quinceañera (fifteenth birthday party). She ties three light silk ribbons together to the top of a gateway and hangs a rubber balloon from each ribbon (Fig. P23.88). To include the effects of the gravitational and buoyant forces on it, each balloon can be modeled as a particle of mass 2.00 g, with its center 50.0 cm from the point of support. Inez rubs the whole surface of each balloon with her woolen scarf, making the balloons hang separately with gaps between them. Looking directly upward from below the balloons, Inez notices that the centers of the hanging balloons from a horizontal equilateral triangle with sides 30.0 cm long. What is the common charge each balloon carries?

A proton (mass 1.67 x 10-27 kg, charge +e) is fired directly at a lithium nucleus (mass 1.16 x 10-26 kg, charge +3e). If the proton's
velocity is 4.79 × 105 m/s when it is far from the nucleus, how far apart will the two particles be when the proton is at rest, just before it
turns around? Assume the nucleus is free to recoil.

4. A hollow spherical shell has internal radius a and external radius b, and is made of material of
uniform density p. Find the gravitational field and the gravitational potential in the three regions
0 b by using (1) the Flux Theorem, and (2) Poisson's equation.
A Geiger counter is a device used to detect radiation, and consists of a thin metal wire (anode) at
the center of a metallic tube (cathode). As radiation enters the tube, electrons are knocked off
from the gas inside the tube or from the metallic wall, and accelerate towards the wire at the
center. Consider a Geiger counter with an evacuated tube (a vacuum existing between cathode
and anode), where the inner anode has a radius 4 mm and the outer cathode has a radius of 82
mm. The anode has a linear charge density of +18 nC/m, while the cathode has a charge per unit
length of -18 nC/m. Let the cathode potential be equal to zero (using it as voltage reference).
What is the potential at a distance of 142 mm from the center? Express your answer up to four
significant figures.

- You are working in a manufacturing plant. In one particular machine, electric charges are suspended above a uniformly charged disk of radius R. The disks become corroded rapidly and must be replaced daily. Your supervisor comes to you one day and tells you that he wants to replace the disks with much cheaper washers of radius R with a concentric hole of radius R/4. He asks you to determine by what factor the charge on the disk must be increased so that a uniform charge on the washer would provide the same electric field at a distance x = R on the central axis as did the disk Answer should be in the form qwasher/qdiskarrow_forwardA particle has a mass of 1.2 × 10-5 kg and a charge of 4 × 10-5 C.
