MULTIPLECHOICE Choose the one alternative that best completes the statement answers the question. The charge carried by one electronis 10-19 C The nuamber of electrons necessary produce a charge of -1 0Cis A) 6.3.109 C 16 100. D) 16 1019. none of the above Apiece of plastic has anetdarge of 200 uc. How many more protons than electrons does this piece of plastic have? BO 1.25.1019 3) The force of attraction between a-400HC and 108 uct charge is 400 N.What is the y separation between these twocharges? 1.13 m B) 2.10 m 4) A 1.0-C charge is 15 m from a second charge, and the foroe between them is 1ON. What is the magnitude of the second charge? A) 25C D) 0.025 C force on the electron A) 1000 C B) 2.9 nN D) 37 nN 9.2 nN ying 2.50 m apart on a table. If each of 6) Two coins carry identical charges. These two coins are these coins experiences a foroe of 2.00 N, how large is the charge on each coin? D) 667 uC A) 26. HC B) 5.22 C 7 Two point charges, initially 2.0 cm apart, experience a 1.0-N force. lfthey are moved to a new separation of 8.0 cm, what is the electric force between them? D) 4.0 N B) 1/16 N A) 1/4 N C) 16 N

Explanation / Answer

here,

charge on electron , q = - 1.6 * 10^-19 C

let the number of electrons be n

n = - 1 C /(- 1.6 * 10^-19 C)

n = 6.3 * 10^18 electrons

the number of electrons are B) 6.3 * 10^18 electrons
