- A charge of 36.3 nC is transferred to a neutral copper ball of radius 4.35 cm. The ball is not grounded. The excess electrons spread uniformly on the surface of the ball. What is the number density (number of electrons per unit surface area) of excess electrons on the surface of the ball?(a) Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 109 electrons already present?Two 25.0-g copper spheres are placed 75.0 cm apart. Each copper atom has 29 electrons, and the molar mass of copper is 63.5463 g/mol. What fraction of the electrons from the first sphere must be transferred to the second sphere for the net electrostatic force between the spheres to equal 100 kN?
- A 2.5-g copper penny is given a charge of 4.0109C . (a) How many electrons ale removed from the penny? (b) If no more than one electron is removed from an atom, what percent of the atoms are ionized by this charging process?Suppose a speck of dust in an electrostatic precipitator has l.0000 1012 protons in it and has a net charge of5.00 nC (a very large charge for a small speck). How many electrons does it have?A typical AA size rechargeable NiMH battery can store 1100-2100 mAh of electric charge. The small print on the battery in your hand says 1530 mAh. Can you express this amount of electric charge using the usual coulomb units? You are now charging a camera battery. The charger moves 4470 C of electric charge from the negative terminal of the battery to the positive terminal. (In reality the charger moves the negative electrons from the positive terminal to the negative terminal, but this is not important for us right now.) Assuming - incorrectly - that the voltage of the battery remains a constant 3.20 V during the whole charging process, determine the work done by the charger. And now you are charging a capacitor bank for a high-voltage physics experiment. The power supply moves Q = 8990 C of electric charge in the charging process. The supply is set to stop, when the voltage reaches AV = 710 V. How much work did the power supply perform?
