True or False questions on Electric Fields

T or F. The E-field,

**E**, at a point in space is the same as the electric force at that point, except for a factor of q.T or F. E-field lines point from negative to positive charge.

T or F. The E-field is a vector.

T or F. Field lines are vectors.

T or F. One can tell where an E-field is strong (in a diagram) by the density of field lines.

T or F. Field lines always cross each other near equilibrium regions.

T or F. If a positively charged particle is released in an electric field, its trajectory will always follow the field lines.

What is a valid unit for

**E**?
