A glass rod rubbed with silk acquires a charge of +1.3*10^-9C, how many electrons have been transferred to the silk?
Q = ne
n = Q/e = 1.3*10^-9/1.6*10^-19 = .8125 * 10^9 electrons = 8125 * 10^5 electrons
Please let me know if you have any questions and best me if you are satisfactory.
how much mass has the glass rod gained or lost?
8125 * 10^5 * 9*10^-31kg
okay so now I have a different question... how do I find the magnitude or the electric field if the only give me the distance between
