TBR Physics II Exam Questions & Answers 2024 *Electrostatics & magnetism* - ANSWER- Coulomb's law - ANSWER- Electric & gravitational forces - ANSWER- When voltage is applied across a wire, a current flows Imagine *e-'s go up V stairs* - ANSWER-*Electrons* move from *lower to higher voltage* (opposite to current "+ charge") The current makes electrons flow into the wire and out of the wire (equalling each other), so the net charge on a wire will not change. The *net charge i...

B. It varies inversely as the distance to the charge. C. It varies directly as the square of the distance to the charge. D. It varies inversely as the square of the distance to the charge. - Answer-D. It varies inversely as the square of the distance to the charge. As a professional engin...

Physics Question and answers already passed Physics ... - correct answer The Coulomb one, in which the divergence of the vector potential is set to zero, is often used when sources are not present. Within the Lorentz one, the divergence of the vector potential plus the product of one over c and the time derivative of the scalar potential is zero. Transformations given this name include, for instance, the addition of the gradient of a scalar function to the vector potential. For 10 point...
