MAGNETISM AND ELECTROMAGNETISM QUIZ

The electric intensity is a vector quantity

The electric field intensity at a point is numerically equal to the force exerted upon a charge placed at that point

An electric field is defined as a point in space at which an electric charge would experience a force

Unit field intensity in the exertion of a force of one newton on a charge of one coulomb

will depend on the radius of the circle

will depend on the amount of e.m.f. applied

will be infinite

will be zero
