State about Electric Field Lines
Electric Field Lines (lines of force) - show direction of force on a positive test charge from a distribution of charges. The electric field points in the direction tangent to the field at any point.
Electric field lines point radially outward for a positive point charge and radially inward for a negative point charge.
The number of lines entering (leaving) a charge is proportional to the magnitude of the charge. (Instance: a charge of +2q will have twice as lots of lines leaving as a charge of +q).
