1. Find the total positive charge of all the protons in 1.0mol of water. 2. Suppose a 1.0g nugget of pure gold has zero net charge. What would be its net charge after it has 1.0% of its electrons removed? 3. C A balloon, initially neutral, is rubbed with fur until it acquires a net charge of 0.60nC. (a) Assuming that only electrons are transferred, were electrons removed from the balloon or added to it? (b) How many electrons were transferred? 4. C A metallic sphere has a charge of +4.0nC. A negatively charged rod has a charge of 6.0nC. When the rod touches the sphere, 8.2109 electrons are transferred. What are the charges of the sphere and the rod now? 5. A hollow metal sphere carries a charge of 6.0C. An identical sphere carries a charge of 18.0C. The two spheres are brought into contact with each other, then separated. How much charge is on each? 6. C A positively charged rod is brought near two uncharged conducting spheres of the same size that are initially touching each other (diagram a). The spheres are moved apart, and then the charged rod is removed (diagram b). (a) What is the sign of the net charge on sphere 1 in diagram b? (b) In comparison with the charge on sphere 1 , how much and what sign of charge is on sphere 2
