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):

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

|
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 |
