Term
 the electrical field produced by a positive charge
Definition
 directs away from charge
Term
 Consider the locations to the right,left,above, and below the positive charge, all 1 m  away,For these four locations, the magnitude of the electric field is _______. Why?
Definition
 the same why: the strength of the electric field due to 1 point charge depends SOLEY on the distance away from the charge.   *Mathematically we say that it is symmetrical.
Term
 the magnitude of the electrical field 1m away from the positive charge is _______ (times/of) the magnitude of the electric field 2m away.
Definition
 4 times GREATER Recall magnitude of the electrical field decreases with increased distance of the charge. Using this equation (Columb's Law): [image] You can calculate
Term
 Which statement best describes the differences in the electric field due to a negative charge as compared to a positive charge?   How does the electric field change when a negative charge is placed in the field? (1) What remains the same?
Definition
 1.The electriclal field now points toward the charge  (remember this based on the fact that a + charge would be attracted to the field) 2. magnitude remains same
Term
 Where does the magnitude of the electrical field roughly equal to zero, when 2 postive charges are placed 1m apart in the electrical field?
Definition
 Near the mid point
Term
 The electrical field at the midpoint btwn a + and - charge is directed to the _____   (postive charge is on the left negative is on the right)
Definition
 right   b/c the neg charge is on the right
