So the total charge on the sphere is (A) ; (B) (C) ; (D) . 2. The wire shown in figure carries current I. So the magnetic field B is produced at the center C of the semicircle by the total wire is (A) 0; (B); (C); (D). 3.Two concentric thin metal shells, radii are andrespectively. If the two shells charged and and their potentials are and respectively. Now if we connect the two shells with conducting wire, their potential is: (A) (B) (C) (D) 4.As shown in figure ,uniform magnetic field is confined in long cylindrical space .If ,so the magnitude of the induced electric field of point p outside the cylinder is: (A) (B) (C) 二、选择题(本题10分，每小题2分) 三、 四、 5. The Maxwell equation which describes the variable electric field will produce magnetic field is (A) (B) (C) (D) 6．As shown in right figure , the magnetic field is placed in the direction of negative direction of y-axis ,if we know that the electric potential difference between a and b , so the material is (A) N type (B) P type (C) metal (D) not certain. 7. Which of the following descriptions of wave function is right? (A) is the probability of finding the particle at position r; (B) is probability density of finding the parti
