Electric Charges 04 - Electric Fields Practice |

OPENING QUESTIONS: WORDS/FORMULAE FOR TODAY Terms:
Constants:
Formulae: - Electrical Force: F
_{e}= (k_{e}q_{1}q_{2})/r^{2} - Electrical Field: E = F
_{e}/ q_{o}where q_{o}= a positive test charge - #1 and #2 (above) work well together to tell us about the
*strength*of the electrical field at some distance (r) away from a point source:E = (k _{e}q)/r^{2}Please keep in mind that E is a vector and that we will frequently need to componentize 'r' in terms of unit vectors *i*and*j*
WORK O' THE DAY: Let's get someone up to dissect the long, thin rod problem.... ═══════════════════════════ Here's a helpful review of efield vectors: physicsclassroom.com) And THIS about efields And THIS about particles in motion in an efield Here is the PHET animation ═══════════════════════════ We haven't covered near enough material for a So...
