Unformatted text preview: 1 PHYS 272 Practice Exam 2 Problem In the diagram below, the electric field is uniform and has components <200, 300, 0> N/C. Point A is at <0, 0, 0> m. B is at <0, 2, 0> m. What is V along a path from A to B? 1. 0 V 2. 300 V 3. 500 V 4. 600 V 5. 1000 V 6. +300 V 7. +500 V 8. +600 V 9. +1000 V X X E A B 3 Problem V BV A = +500 V. V CV B = 200 V. What is V CV A ? 1. +700 V 2. +300 V 3. 0 V 4. 300 V 5. 700 V X X X A B C 4 Problem A bar magnet has a length L, cross sectional area A and magnetic dipole moment of = 8 Am 2 . It is cut into two equal pieces, each with length L/2 and cross sectional area A. Each of these bar magnets has a magnetic dipole moment 1 . The ratio 1 / is: 1. 1.0 2. 2.0 3. 4.0 4. 0.5 5. 0.25 6. No enough information Problem An electron and a proton are near each other, moving with velocities as shown in the plane of the page. What is the direction of the magnetic force on the electron due to the proton? 1. Out of the page 2. Into the page 3. 4. 5. 6. 7. No force on electron due to proton at this instant v e v p x 5 Problem There are two coils separated by a large distance 2 L ( L >> R , R is the radius of the coil). The xaxis passes through the center of each coil and the plane of each coil is perpendicular to the xaxis. In one coil the conventional current flows clockwise while in the other the conventional current flows counter clockwise. the other the conventional current flows counter clockwise....
