Multiplechoice questions may continue on the next column or page – find all choices before answering. Charge in Water 001 10.0 points You have 3 . 6 kg of water. One mole of water has a mass of 18 . 1 g / mol and each molecule of water contains 10 electrons since water is H 2 O. What is the total electron charge contained in this volume of water? Correct answer: 1 . 91644 × 10 8 C. Serway CP 15 11 002 (part 1 of 2) 10.0 points Three charges are arranged in a triangle as shown. + + . 342 m . 753 m 5 . 57 nC 3 . 24 nC 1 . 6 nC y x What is the net electrostatic force on the charge at the origin? The Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . Correct answer: 1 . 3939 × 10 − 6 N. 003 (part 2 of 2) 10.0 points What is the direction of this force (as an angle between 180 ◦ and 180 ◦ measured from the positive xaxis, with counterclockwise posi tive)? Correct answer: 95 . 8165 ◦ ....
