FinalPracticeexam2 PHY184 - 1 1 pt Figure A shows four charges in a plane, with an xy coordi- nate system. Determine the electric ±eld at the origin O. Data: q = 1 . 0 × 10 - 6 C; a = 2 . 0 × 10 - 2 m. 1 . A ± 9 . 0 × 10 5 N/C B ± 4 . 5 × 10 5 N/C C ± 2 . 25 × 10 7 N/C D ± 9 . 0 × 10 7 N/C E ± 0 F ± 4 . 5 × 10 7 N/C 1 pt Figure A shows four charges in a plane, with an xy coordinate system. Determine the electrostatic potential at the origin O. Data: q = 1 . 0 × 10 - 6 C; a = 2 . 0 × 10 - 2 m. 2 . A ± 9 . 0 × 10 5 V B ± 0 C ± 4 . 5 × 10 5 V D ± 2 . 25 × 10 7 V E ± 4 . 5 × 10 7 V F ± 9 . 0 × 10 7 V 1 pt The Figure shows equipotential curves of a system of three charges in a plane that contains all three particles. Estimate the electric ±eld at the point P, whose coordinates are (0,0). (The coordinates in the ±gure are measured in centimeters.) 3 . A ± 4000 V/m in the +x direction B ± 20 V/m in the -x direction C ± 4000 V/m in the -x direction D ± 20 V/m in the -y direction E ± 20 V/m in the +y direction F ± 4000 V/m in the +y direction G ± 4000 V/m in the -y direction H ± 20 V/m in the +x direction

FinalPracticeexam2 PHY184 - 3 1 pt Figure C shows two charged spheres; q 1 = 2 . 0 × 10 - 6 C and q 2 = 3 . 0 × 10 - 6 C. Charge q 1 is at the origin and charge q 2 is at the point ( x, y, z ) = (0 , 0 , a ) where a = 5 cm. Determine the fux o± electric ²eld through the sphere, which has radius 2 a . 4
