部分真題預覽：

1）Two point charges,q_1?and q₂, are fixed in place on the x-axis at positions x₁ =? -1.00m?and x₂ = +0.50m, respectively. Charge q₂ has a value of +0.2nC. Values of electric potential are illustrated by the given equipotentials in the diagram shown above, which is drawn to scale.

1. Calculate the value of q₁.
2. At point C on the diagram, draw a vector representing the direction of the electric field at that point.
3. Calculate the approximate magnitude of the electric field strength at point D on the diagram.
4. The equipotential labeled 0 V is the cross p of a nearly spherical surface. Calculate the electric fluxfor this surface.
5. A proton is placed at point A and then released from rest.
   1. Calculate the work done by the electric field on the proton as it moves from point A to point E.
   2. Calclulate the speed of the proton when it reaches point E.
6. An electron is released from rest at point B. Which of the following indicates the direction of the initial acceleration, if any, of the electron?
   _____Up_____Down
   _____Left_____Right
   ______Into the page______Out of the page
   ______The direction is undefined since the acceleration is zero.
   Justify your answer.
