Question

The electric field at a point in space is defined as


a scalar proportional to the force that acts on a small positive test charge placed at that point.
a vector in the direction of the force that acts on a small negative test charge placed at that point.
a vector in the direction of the force that acts on a small positive test charge placed at that point. The magnitude of the field is given by the product of that force with the test charge.
a scalar proportional to the force that acts on an electron (negative charge) placed at that point.
a vector in the direction of the force that acts on a small positive test charge placed at that point.

Explanation / Answer

I'll give you the actual definition. Then you can use that to answer your homework question. E = F/q. Electric field is the force per unit charge. F is a vector, so if q is positive, E is a vector pointing in the same direction as F.
