Chapt. 22 Electric Charge Multiple-Choice Problems 022 qmult 00100 1 1 1 easy memory: electric charge definition, incomplete Extra keywords: physci 1. Electric charge is: a) a fundamental property of matter: it comes in invariant quantized amounts of size ± e . b) a derived property of matter: it comes in somewhat variable quantized amounts of size ± e more or less. c) a fundamental property of matter which comes in a continuum of quantities: there is no smallest bit of charge. d) a derived property of matter which comes in a continuum of quantities: there is no smallest bit of charge. e) amber. 022 qmult 00110 1 1 5 easy memory: Ben Franklin named charges Extra keywords: physci KB-137 2. Who named positive and negative electric charge? a) George Washington (1732–1799). b) John Adams (1735–1826). c) Benedict Arnold (1741–1801). d) Aaron Burr (1756–1836). e) Benjamin Franklin (1706–1790). 022 qmult 00120 1 1 1 easy memory: elementary charge 1 Extra keywords: physci KB-169-1 3.
