1)You can use an electroscope in the lab to determine the relative magnitude of charge on objects charged by rubbing. You however couldnot be expected to know the sign of the charge and must therefore be given that information for two combinations (ie. rubbing a glassrod with silk resulted in a net positive charge on the glass rod while rubbing plastic rod with wool resulted in a net charge on the plasticrod). From those facts you were able to determine the sign of charge on an unknown, when using a charged electroscope.Draw a positively charged electroscope below and clearly indicate the position of the leave(s).Positively Charged:a)b)c)Neutral:Draw the charge distribution on the positively charged electroscope above.Now consider a highly charged rod being held close to the electroscope and indicate in a diagram the distribution of the chargeon the electroscope if the leaves end up separating by about 45degrees.

Two spherical objects are separated by a distance of 1.52 x 103 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 2.24 x 10-20 N. How many electrons did it take to produce the charge on one of the objects? Number Units
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +6q. Sphere B carries a charge of -5g. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Last, sphere C is touched to sphere B and separated from it. For the following questions, express your answers in terms of q. (a) How much charge ends up on sphere C? 0.5 (b) What is the total charge on the three spheres before they are allowed to touch each other? 0.25 (c) What is the total charge on the three spheres after they have touched? 0.375 Additional Materials M eBook JAN 12 tv MacBook Air DII 80 F7 F8 F6 esc F4 F5 F1 F2 F3 * 24 %

When you rub a glass rod with silk you electrically charge the glass rod (and the silk). Likewise, when you rub a plastic rod with fur you electrically charge the plastic rod (and the fur). However, when you place the charged rods near each other you notice that they attract. What can you conclude about the sign of the charge on each? Can you determine just from this experiment the sign of the charge on each rod? Yes, they have equal charges, either positive or negative. Yes, the have opposite charges, the glass rod is negative and the plastic rod is positive. Yes, the have opposite charges, the plastic rod is negative and the glass rod is positive. If the two rods attract each other, then we can conclude that they have opposite charges. However, we cannot conclude from this experiment alone which one is negative and which one is positive. SInce the two rods attract each other they must have like charges, because like charges attract.…
A charge Q is attached to each of two diagonally opposite corners of a square. A charge q is placed on each of the other two corners. a) If the resultant of the electrical forces acting on Q is null, what is the relationship between the charges Q and q? b) Could we choose a value of q such that the resultant on any of the other charges is null? Explain.
Two objects charged with an equal amount of charge interact with each other with a force of 4.81 Newton when separated by a distance of 16.9 cm. Determine the magnitude of the charge on each object. Answer:_______x10-6 C Enter only the coefficient of the scientific notation. For example, you'd enter just just 1.27 if you get 1.27x10-⁹.
b) Calculate the net force (magnitude and direction) exerted on charge q by the other four charges, in terms of q, Q, d, and e0. You may draw the force vector to indicate the direction. c) If the charge q is released from rest, and the four other charges held fixed, will the charge q ever “escape” to infinitely far away (assuming an infinite amount of time can pass)? Justify your answer.

In the picture below, the rod is positively charged. Electrically speaking, water is a "polar molecule"; each water molecule can be imagined as a negative charge (the oxygen end) and a positive charge (the hydrogen end), each of approximate magnitude 2e, separated by an approximate distance of 2 x10-1" m. a) Explain how a charged rod can exert an electric force on water molecules that have zero net charge. Include a picture of a typical water molecule in the stream of water adjacent to the rod, showing its orientation relative to the rod. b) If the charge of the rod is +32 nC and that charge is located approximately 2.0 cm from a water molecule in the stream, what is the maximum possible net electric force that the rod could exert on the molecule?
I would like to have a factual solution and answer here please? thank you. Two point charges are placed on the x-axis as follows: Charge ?1 = +4.00 nC is located at ? = 0.200 m, and charge ?2 = +5.00 nC is at ? =−0.300 m. What are the magnitude and direction of the total force exerted by these two charges on a negative point charge Charge ?3 = −6.00 nC that is placed at the origin?
