部分真题预览：

1）A proton moving along the positive x-axis enters an electric field that is directed along the positive y-axis. What is the direction of the electric force acting on the proton after it enters the electric field?

1. Along the negative z-axis
2. Along the positive z-axis
3. Along the negative y-axis
4. Along the positive y-axis
5. The direction cannot be determined since the magnitude of the electric field is not known.

5）All the following statements about an isolated, solid charged conductor are correct EXCEPT:

1. All parts of the conductor are at the same potential.
2. All excess charge resides on the outer surface.
3. The net charge enclosed by any surface lying entirely within the conductor must equal zero.
4. The electric field E just outside the conductor is directed parallel to the surface.
5. The electric field intensity inside the conductor is zero.

9）A proton moving to the right at constant speed u enters a region containing uniform magnetic and electric fields and continues to move in a straight line. The magnetic field B is directed toward the top of the page, as shown above. The direction of the electric field must be

1. into the page
2. out of the page
3. to the left
4. toward the top of the page
5. toward the bottom of the page
