Question

Answer both questions 1 and 2 please.

The Origin of Electricity An object carries a charge of -8.0 mu C. while another carries a charge of - 2.0 mu C. How many electrons must be transferred from the first object to the second so that both objects have the same charge? Charged Objects and the Electric Force Each of three objects carries a charge. As the drawing shows, objects A and B attract each other. and objects C and A also attract each other. Which one of the following statements concerning objects B and C is true? (a) They attract each other. (b) They repel each other. (c) They neither attract not repel each other. (d) This question cannot be answered without additional information. Charging by Contact and by Induction

Explanation / Answer

1. ( 8 + 2) /2 = 5 microcoulumbs each So 3 uC must be transferred from the greater charge to the smaller one 3 x 10^-6 x 1 electron/1.6 x 10^-19 = 1.875 x 10^25 electrons 2. B SInce B and C are both attracted to A, they are the same charge and would thus repel each other
