Horatio rubs an inflated balloon against his hair. He then touches the balloon against a non-conducting wall. The picture that most clearly represents the charge distribution on the balloon and wall is: WALL WALL WALL WALL BALLOON BALLOON BALLOON BALLOON A

Particles A and B collide to produce particles C, D, and E: A+B ---> C +D+E. A has a charge of le, B has no charge, C has a charge of -2e, and D has a charge of 1e. What charge does E have? -2e -e +2e none of these

Identify the following statements as either TRUE or FALSE    Both conductors and insulators can become charged    Electrons move easily in conductors but not in insulators.    The magnitudes of the charges of protons and electrons are different (not just the signs of the charge)    Most everyday objects contain significantly more negative charges than positive charges

When a glass rod is pulled along a silk cloth, the glass rod acquires a positive charge and the silk cloth acquires a negative charge. The glass rod has 0.27 µC of charge per centimeter. Your goal is to transfer 1.0 1013 electrons to the silk cloth. How long would your glass rod need to be when you pull it across the silk? (Assume the rod is flat and thin). cm

Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting -50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 31 steps? charge buildup from 31 steps: How many electrons are present in that amount of charge? electrons present: nC maximum number of steps: electrons If a delicate manufacturing process can be damaged by an electrical discharge greater than 1012 electrons, what is the maximum number of complete steps that any worker should be allowed to take before touching the components? steps

A 5 g dust particle has a charge of 7 ?C and is suspended between two oppositely charged parallel plates as shown below. The distance between the particle & the edges of the plates is much greater than the distance between the plates. Each plate has the same constant uniform charge density. (note: Top plate is negative and bottom is positive) Find the voltage between the plates. V=

Bead A has a mass of 15 g and a charge of -5.2 nC . Bead B has a mass of 22 g and a charge of -11.7 nC . The beads are held 15 cm apart (measured between their centers) and released.

A positively charged balloon is brought near a neutral, conducting sphere. The opposite side of the conducting sphere is touched. When touched, electrons move _____. from the sphere to the hand from the hand to the sphere to the balloon from the sphere to the balloon from the hand to the sphere

An oil droplet is given a very small amount of charge. Which of the following could not be the amount of charge that it has? 7.8x10^-19C O 6.4x10^-19C 3.2x10^-19C O 1.6x10^-19C

The electroscope is an apparatus used to detect electric charge. The electroscope consists of a plate, a support and thin metal foil that is free to deflect all made of metal. After rubbing a balloon on your sleeve, the negatively charged balloon is brought near to the metallic plate of an electroscope. As a result, the foil of the electroscope deflects.     As the balloon approaches the electroscope, what is the net charge on the electroscope?     Negative  Positive  Neutral  Cannot be determined
