Help with Part C. Please show all your work. I have already tried d=V/E= 7/[(2.9x10^-9)/2(8.85x10^-12) A very large sheet of insulating material has had an excess of electrons placed on it to yield a surface charge density of -4.00 nC/m2. (a) As the distance from the sheet increases, does the potential increase or decrease? (e) increase O decrease Can you explain why without any calculations? The electric field points in the direction of increasing potential while pointing away from negative...
A proton is released from rest at the positive plate of a parallel plate capacitor. The charge per unit area on each plate is σ=1.8e-7 C/m2 , and the plates are separated by a distance of 1.5e-2 m. a. What is the magnitude of the electric field between the two plates? b. What is the potential difference between the two plates? c. The line connecting A and C is perpendicular to the electric field lines. The distance between A and...

Learning Goal: To be able to interpret potential energy diagrams and predict the corresponding motion of a particle. Potential energy diagrams for a particle are useful in predicting the motion of that particle. These diagrams allow one to determine the direction of the force acting on the particle at any point, the points of stable and unstable equilibrium, the particle's kinetic energy, etc. Consider the potential energy diagram shown. (Figure 1) The curve represents the value of potential energy U...
D. Since the proton is moving while feeling a force, work is done on the proton: Won P = Felec Mlax Icoso, where lax is the magnitude of the proton's displacement and is the angle between the direction of that displacement straight to the left in this case) and the direction of the force on the proton. While the proton is approaching the nucleus the work done on it is positive, negative, zero). Important: our attention is now focused on...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
b. For the above to be true, the constant term e must be related HOW to the constants 0 and K ? (Write down an equation that includes all four constants.) (3 pts.) c. Show how v, the speed at which one pulse (or crest or trough, etc.) of the wave propagates, can be expressed in terms of your finding in (b). Show reasoning, not just a final answer (3 pts). w = angular frequency = number of cycles per...
