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? Figure P23.88

Solution Summary: The author explains the common charge on each balloon, and the diagram for the equilateral triangle formed by balloons.

An old model of a hydrogen atom has the charge +e of the proton uniformly distributed over a sphere of radius a0, with the electron of charge -e and mass m at its center. (a) What would then be the force on the electron if it were displaced from the center by a distance r # a0? (b) What would be the angular frequency of oscillation of the electron about the center of the atom once the electron was released?
Two electrons in a vacuum exert force of F = 4.63E-08 N on each other. They are then moved so that they are separated by x = 6.4 times their original distance.
a. What is the force, in newtons, that the electrons experience at the new separation distance?
b. How far apart, in meters, were the electrons originally?
(a) A uniform electric field of strength E = 7.91 N/C passes through a flat surface at an angle of 24.5° (that is, the angle it makes with the area vector is 24.5°). The electric flux is 6.15 (N/C)·m2. What is the area of the surface? (b) A uniform electric field of strength E = 334 N/C passes through a flat surface at an angle of 0.880 radians. The electric flux is 455 (N/C)·m2. What is the area of the surface?
