A 25-g copper penny is given a charge of-4.0 penny? 10-9 C. How many excess electrons are on the x 9.426 x 1010 electrons 4.296 x 1010 clectrons 2. 496 x 1010 electrons 1.946 x 1010 electrons Question 2 (12.5 points) atomic nucleus are typically 10-15 m apart. What is the electric force of repulsion between Protons in a nuclear protons? 320.7 N 430.7 N 230.7 N 130.7 N
P. A copper penny has a mass of 2.5 g. Suppose it has a net charge of +1.2 nC. How many electrons has it lost? What fraction of the total number of electrons in an uncharged penny is this?
Suppose that the negative charge in a copper one-cent coin were removed to a very large distance from Earth-perhaps to a distant galaxy-and that the positive charge were distributed uniformly over Earth's surface. By how much would the electric potential at the surface change? (See Sample Problem 22-7 in the problem supplement. By taking the mass of a penny to be 3.11 g, the positive or negative charge is found to be 1.37×105 C)

A 2.5 gram penny is given a charge of -4.0 *10^-9 c. How many excess electrons are on the penny?
1) How many excess electrons are required for an object to carry a charge of 1pC (10^-12 C)? 2) You remove 2x10^10 electrons from a quarter and the same number from a penny. Do the coins end up with a net positive charge or a net negative charge? which coin ends up with the greater net charge? explain.
How many electrons does it take to have a total charge of -1.00 coulombs?
Question 3-8 points To the best of our knowledge the magnitudes of the negative charge on the electron and the positive charge on the proton are precisely equal. Imagine for the purposes of this question, however, that the charge on the proton is slightly larger than the charge on the electron (a) Do some research and determine (i) the number of electrons and the number of protons in a copper atom, and (ii) the mass of a copper atom. (2...
