Unformatted text preview: 192 Chapt. 25 Electric Potential 8. Lets play Jeopardy ! For $100, the answer is: It is the energy an elementary charge acquires if accelerated through a 1 V potential. What is a/an , Alex? a) joule b) electronvolt or eV c) electron-joule or eJ d) kilo-electronvolt or KeV e) mega-electronvolt or MeV 025 qmult 00220 1 4 1 easy deducto-memory: electronvolt calculation 9. If an electron is accelerated through a potential difference of 100 V, what kinetic energy does it acquire in eVs (electronvolts)? a) 100 eV. b) 0 . 01 eV. c) 1 . 6 10 17 eV. d) 1 . 6 10 17 J. e) 1 . 6 10 17 eV. 025 qmult 00230 1 3 4 easy math: fiducial electronvolt speed 10. Say an electron is accelerated from rest through a 1 V potential. What is its final speed? a) 1 10 5 m / s. b) 3 10 5 m / s. c) 3 10 8 m / s. d) 6 10 5 m / s. e) 6 m / s. 025 qmult 00300 1 1 4 easy memory: differential potential change 11.
