Consider a positive source charge Q, that is being held in place. A nearby negative test charge q moves from point A to point B.
a) What is the direction of the electric force that the source charge exerts on the test charge?
b) As the negative test charge moves from point A to point B, does the electric force cause it to speed up, slow down, or move at a constant velocity?
c) As the negative test charge moves from point A to point B, does its electric potential energy increase, decrease or remain the same? (What happens to its kinetic energy?)
d) What is the direction of the electric field that the positive source charge creates at points A and B?
e) Which point has a higher electric potential created
by the postive source charge?

Theory Electric field is a measure of the degree to which a source charge Q distorts its surrounding space. As a result of this distortion, the motion of other charges q are driven by the electric force Fe the source charge exerts on them. In this regard, electric field is defined as the ratio of the force (which the source charge Q exerts other charge q) to charge q: F Ē 9 The direction of electric field at a point...
