下面是两道SAT2物理题及问题的答案。SAT2物理考试相对于其他的SAT2考试科目而言是比较简单的，所以大家在备考SAT2物理考试的过程中，一定要更加关注方法的积累，这样才能更加有效率的解答关于SAT2物理方面的题目。

　　The set of lettered choices below rers to multiple questions. Select the one lettered choice that best answers each question. A choice may be used once, more than once, or not at all in each set.

　　This question relates to a point charge fixed in position, as shown in the diagram. Five points near the charge and in the plane of the page are shown.

　　At which point will the magnitude of the electric field be least?

　　Answer Choices

　　(A) Point A

　　(B) Point B

　　(C) Point C

　　(D) Point D

　　(E) Point E

　　The correct answer is D

　　Explanation

　　Difficulty: Easy

　　The correct answer is point D because it is farthest away from the point charge. The magnitude of the electric field E at any location due to a point charge is inversely proportional to the square of the distance r from the location to the charge,, so the greater the distance, the less the magnitude of the electric field.

　　This question relates to a point charge + Q fixed in position, as shown in the diagram. Five points near the charge and in the plane of the page are shown.

　　At which point will an electron experience a force directed toward the top of the page?

　　Answer Choices

　　(A) A

　　(B) B

　　(C) C

　　(D) D

　　(E) E

　　The correct answer is E

　　Explanation

　　Difficulty: Easy

　　The correct answer is point E, which is directly below the point charge + Q. The electron is negatively charged and since unlike charges attract, it will always experience a force directed straight toward the charge + Q, which is fixed in position. The only labeled point where a force toward + Q is directed toward the top of the page is point E.

　　以上就是这两道SAT2物理题的全部内容，是关于一幅图的两道题目，后面附有答案解析和问题的难度。SAT2物理题和大家平时解答的物理题目有所不同，所以需要大家不断的练习才能在词汇和方法方面都熟悉掌握。
