Let's say two unknown charges are given to you. You do not know their individual charges, but you know that their total charge is 8.00µC. You made a test in the laboratory and found that these two charges push each other away with a force of 0.150 N when separated by 0.500 m. What is the charge of the "higher charge" in units of µC ?
Two identical, small insulating balls are suspended by separate 0.21-m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.7 × 10-4 kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 50° between the threads. Determine (a) the charge on each ball and (b) the tension in the threads. A F₁
Two otherwise identical conducting spheres carry charges of +4.80 µC and –1.00 µC. They are initially a distance L apart. The distance L is much larger than the radii of the spheres. The spheres were brought together, touched, and then returned to their original separation L. What is the ratio of the magnitude of the force on either sphere after they are touched to that before they were touched?
A very thin glass rod 4 m long is rubbed all over with a silk cloth (see figure below). It gains a uniformly distributed charge +4.2 x 10-6 C. Two small spherical rubber balloons of radius 1.2 cm are rubbed all over with wool. They each gain a uniformly distributed charge of -6.7 x 10-8 C.
