Module 4 Flashcards
Area where electrical force can be experienced by stationary point charge in a location in a field.
Electric Field
T/F
An uncharged body creates an electric field. Charges create and experience the electric field of each other.
False (All charged bodies create an electric field)
The electric field points ____ from a positive charge and _____ a negative charge
away; toward
Who introduced Electric Field lines?
Michael Faraday
An electric field line is an imaginary line or curve drawn through a region of ____ space.
Empty
2 equal charges with opposite signs is called a/an ___?
Electric Dipole
T/F
The denser the lines and the more lines, the stronger the electric field?
True
An electric field points in the direction ___ to the field line at any point
tangent
T/F
Field lines can cross?
False (Field lines do not cross because electric fields can’t have 2 directions at the same point.)
The magnitude of the electric field acting upon a point charge is given by what law?
Coulomb’s Law
A positive charge goes ____ an electric field while a negative charge goes _____.
along; against
If a source charge is positive, the force on a test charge is directed ___.
away
If a source charge is negative, the force on a test charge is directed ___.
towards
