The magnitude of an electric field due to a point charge q
at a distance r away depends on the strength of the charge of a test particleTrueFalseSlide3
Positively charged objects
transfer positive charge to the earth when grounded.TrueFalseSlide4
The magnitude of an electric field is measured in SI units
CNC/N
