The amount of force exerted on a unit positive charge in an electric field is known as _____
a) Electric field intensity
b) Electric flux
c) Electric potential
d) Electric lines of force
Explanation: The zone near a charge where its attraction or repulsion force works, is known as the electric field of that charge. Theoretically, it is up to infinite but practically it has limitations. If a unit positive charge is kept in that field, it will undergo some force which is known as electric field intensity at that point.
