Question

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?

Explanation / Answer

A) away from positive charge b) decreases c) decreases d )away from positive charge e)the point close to positive charge has high potential
