3 cards from this section. Quick, good the night before a test.
Define what an electric field is in your own words.
Think about the area around a magnet and how it can affect other magnetic objects.
What is the formula for electric field strength?
Remember how force relates to charge in a field.
What formula represents the electric field due to a point charge?
Remember the constants that relate to point charges.
True or False: The electric field points away from negative charges.
Think about how forces work in relation to charge types.
A point charge of +5 μC is located at the origin. Calculate the electric field strength at a point 3 meters away and determine the direction of the field.
Apply the formula correctly and clarify the direction based on the charge sign.
Two equal point charges of +2 μC are placed 1 meter apart. What is the electric field strength at a point halfway between the two charges?
Analyze the contributions from each charge based on distance and construct a combined field.
