Three small spheres 91, 92 and 43 are located inside closed surfaces with cross-sections shown in the figure below. All of the three spheres carry the same amount of charge, but the sphere q2 is negatively charged while the other two spheres, q1 and q3, are both positively charged. Which of the following closed surface is the net electric flux greatest in magnitude? S3 SA 091 S₁ OSs (yellow) O None of the given choices O S3 (green) OS₂ (blue) OS (violet) 93 092 S2 S5 Surface What it encloses S₁ S2 S3 S4 S5 91 92 92 91 and 91 and 93 91 and 92 and 93
A charged particle is moving inside a region of constant electric potential. Which of the following bests describes its motion? 1. The particle is speeding up. II. The particle is slowing down. III. The particle has uniform velocity. Ill only cannot be determined I only Oll only
A negatively-charged particle is moved at constant speed from point A to point B. The electric potential at point B is lower than that at point A. The total work done on the particle must be O negative. O zero. O equal to the change in the particle's potential energy. O positive.
The electric potential energy of an electron at point A is UA." while its potential energy at point B is UB. and UA UB. From point A to point B, the electric potential none of the given choices. O increases. O decreases O remains the same
Consider a closed surface S fully enclosing the point charge Q. Which of the following is true about the net electric flux through S? O The electric flux magnitude depends on location of Q inside of S. O None of the given choices. The electric flux magnitude depends on the value of the total surface area of S. The net electric flux magnitude depends on the shape of S.. The net electric flux magnitude depends on value of Q
