Electric Field Questions 1. If you let go of the test charge, the electric force will cause it to move to E8, the area of lower potential. 2. The electric potential of the test charge at point A before it moves is 6 V. 3. As the test charge moves from point A to B, the new potential is 4.5 V. 4. The potential difference between points A and B is 1.5 V. 5. The electric potential energy U at point A is 6x10 -6 J. [U = qV = (1.0x10 -6 C * 6 V)] 6. U at point B is 4.5x10 -6 J. [U = qV = 1.0x10 -6 C * 4.5 V)] 7. The electric potential energy has decreased from point A to B. 8. The kinetic energy has increased in going from rest at point A to whizzing past point B. 9. If you put a finger on the test charge, stop it, and hold it at point B then leg to, the force it experiences is greater than it was at point A. as the distance decreases, the force increases according to the equation for electrostatic force [F = (k* (q 1 q 2 / r 2 )] 10. The strength of the electric field at point B is greater than the strength at point A.
